The MAX14912/MAX14913 have eight 640mA smart high-side switches that can also be configured as push-pull drivers for high-speed switching. The propagation delay from input to switching of the high-side/low-side drivers is 1µs (max). Each high-side driver has a low on-resistance of 230mΩ (max) at 500mA load current at TA = 125°C.The device is configured and controlled either through pins or the SPI interface. The SPI interface is daisy-chainable, which allows efficient cascading of multiple devices. SPI also supports command mode, for the highest detailed diagnostic information. The MAX14912 allows configuration through SPI in parallel and serial setting modes, while the MAX14913 only supports configuration through SPI in serial setting mode.Open-load detection in high-side mode detects both open-wire conditions in the switch on/off states, and LED drivers provide indication of per-channel fault and status conditions. Internal active clamps accelerate the shutdown of inductive loads fast in high-side mode.The MAX14912/MAX14913 are available in a 56-pin QFN 8mm x 8mm package.ApplicationsBuilding AutomationIndustrial Digital OutputsPLC Systems

The MAX15093/MAX15093A ICs are integrated solutions for hot-swap applications requiring the safe insertion and removal of circuit-line cards from a live backplane. The devices integrate a hot-swap controller, 3.8mΩ power MOSFET, and an electronic circuit-breaker protection in a single package.The devices integrate an accurate current-sense circuitry and provide 160µA/A of proportional output current. The devices are designed for protection of 2.7V to 18V supply voltages.These devices implement a foldback current limit during startup to control inrush current lowering di/dt and keep the MOSFET operating under safe operating area (SOA)conditions. After the startup cycle is complete, on-chip comparators provide VariableSpeed/BiLevel™ protection against short-circuit and overcurrent faults, and immunity against system noise and load transients. The load is disconnected in the event of a fault condition. The devices are factory calibrated to deliver accurate overcurrent protection with ±10% accuracy. During a fault condition, the MAX15093 latches off, while the MAX15093A enters autoretry mode.The devices feature an IN-to-OUT short-circuit detection before startup. The devices provide a power-MOSFET GATE pin to program the slew rate during startup by adding an external capacitor. The devices have overvoltage/undervoltage input pins that can detect an overvoltage/undervoltage fault and disconnect the IN from the OUT. Additional features include internal overtemperatureprotection, power-good output, and fault-indicator output.The MAX15093/MAX15093A ICs are available in a 40-bump, 2.57mm x 4.03mm, power wafer-level package (WLP) and are rated over the -40°C to +105°C extended temperature range.ApplicationsDisk Drive PowerIndustrialRAID SystemsServer I/O CardsStorage Bridge Bay

The MAX16150 is an extremely low-power, pushbutton, on/off controller with a switch debouncer and built-in latch. This device accepts a noisy input from a mechanical switch and produces a clean, latched output, as well as a one-shot interrupt output, in response to a switch closure exceeding the debounce period at active-low PB_IN. A switch closure longer than shutdown period at active-low PB_IN results in a longer one-shot interrupt output. The MAX16150 family has two set of devices, one in which a longer switch closure greater than the shutdown period deasserts the latched output, and another in which the latched output stays asserted. See Table 1 for more information.The MAX16150 operates from a supply range of +1.3V to +5.5V and consumes less than 20nA of supply current to ensure minimal battery drain in low-power applications, as well as to allow use as a battery 'freshness seal'. The robust switch input (active-low PB_IN) accepts up to ±60V levels and is ±15kV ESD-protected for use in harsh environments. The latched output can serve as a logic signal to control a regulator, or it can serve as a switch to connect the load directly to the power supply when load current is low, providing 20mA of output current with less than 100mV voltage drop. A separate active-low INT output provides a system interrupt whenever a valid pushbutton signal is detected. An asynchronous active-low CLR input allows an external signal to force the latched output to the off state.The MAX16150 operates over the -40°C to +125°C temperature range and is available in a 1mm x 1.5mm, 6-bump wafer-level package (WLP) and a 6-pin thin SOT23 package.Also see: nanoPower Technology ›ApplicationsDisposable Low-Power ElectronicsHandheld Consumer ElectronicsIndustrial EquipmentPortable Instruments

The MAX16160 precision, four-channel supervisory circuit is designed to maintain system integrity in multi-supply systems.The device monitors its own power supply voltage in addition to three other system supply voltages and asserts the reset output whenever any supply voltage falls below its reset threshold. After all of the supply voltages rise above their reset thresholds, the reset output remains asserted for the reset timeout period, and then de-asserts.During power-up, and before all of the input voltages exceed their trip thresholds, the reset output asserts low if any of the monitored inputs is greater than 1V. The open-drain output has a weak 18μA (typ) pullup to IN2/VCC, eliminating the need for external pullup resistors.The MAX16160 offers a wide range of threshold options. Input thresholds may be fixed or adjustable. Fixed reset voltage thresholds for IN1, IN3, IN4 are available from 0.5V to 5V in approximately 20mV increments. Reset voltage thresholds for IN2/VCC are available from 1.76V to 5V in approximately 20mV increments.The MAX16160 operates over the -40°C to +125°C temperature and is available in a small, 6-bump WLP and 6-pin SOT23 package.ApplicationsData Storage EquipmentDesktop and Notebook ComputersHigh-End PrintersIndustrial EquipmentNetworking EquipmentServers/WorkstationsSet-Top BoxesTelecommunications
