The LTC4358 is a 5A ideal diode that uses an internal 20mΩ N-channel MOSFET to replace a Schottky diode when used in diode-OR and high current diode applications. The LTC4358 reduces power consumption, heat dissipation, and PC board area. The LTC4358 easily ORs power supplies together to increase total system reliability. In diode-OR applications, the LTC4358 regulates the forward voltage drop across the internal MOSFET to ensure smooth current transfer from one path to the other without oscillation. If the power source fails or is shorted, a fast turnoff minimizes reverse current transients.Applications N+1 Redundant Power Supplies High Availability Systems Telecom Infrastructure Automotive Systems

The LTC4110 is a complete single chip, high efficiency, flyback battery charge and discharge manager with automatic switchover between the input supply and the backup battery or super capacitor. The IC provides four modes of operation: battery backup, battery charge, battery calibration and shutdown. Battery backup and battery charge are automatic standalone modes, while the optional calibration mode requires a CPU host to communicate over an SMBus. During calibration the flyback charger is used in reverse to discharge the battery with a programmable constant current into the system load eliminating heat generation. Three status outputs can be individually reconfigured over the SMBus to become GPIOs. User programmable over-discharge protection is provided. The SHDN pin isolates the battery to support shipping the product with a charged battery installed. Multiple LTC4110s can be combined to form a redundant battery backup system or increase the number of battery packs to achieve longer backup run times. The LTC4110 is available in a low profile (0.75mm), 38-pin 5mm × 7mm QFN package. The QFN features an exposed metal die mount pad for optimum thermal performance.Applications Backup Battery Systems Server Memory Backup Medical Equipment High Reliability Systems

The ADM13307 is a triple voltage supervisor designed to monitor up to three voltage levels in DSP and microprocessor-based systems.There are five models available, all of which feature a combination of internally pretrimmed undervoltage threshold options for monitoring 1.8 V, 2.5 V, 3.3 V, and 5 V supplies. There are also two adjustable input options with undervoltage thresholds of either 0.6 V or 1.25 V.The ADM13307-18, ADM13307-25, and ADM13307-33 models have two internally fixed thresholds and one externally programmable threshold via a resistor string. The ADM13307-4 and ADM13307-5 offer one internally fixed threshold and two externally programmable thresholds. See the Data Sheet Ordering Guide for a list of all available options.During power-up, RESET is asserted when the supply voltage exceeds 1.1 V. The device then monitors the SENSEv input pins and holds the RESET output low as long as the SENSEv pins remain below the rising threshold voltage, VIT+.Once the supplies monitored at the SENSEv inputs rise above their associated thresholds, the reset signal remains low for the reset timeout period before deasserting. Subsequently, if a voltage monitored by the SENSEv pins falls below its associated falling input threshold voltage, VIT−, the RESET output asserts.The ADM13307 features both an active high RESET and an active low RESET output.The manual reset input of the ADM13307 can be used to initiate a reset by means of an external push button or logic signal.The ADM13307 is available in an 8-lead narrow body SOIC package. The device operates over the extended industrial temperature range of −40°C to +85°C.APPLICATIONS Supervising DSPs/microcontrollers Industrial and portable equipment Wireless systems Notebook/desktop computers

The ADM6711 / ADM6713 are reset generator circuits suitable for use in microprocessor-based systems. They provide a reset signal on power-up, power-down, and whenever the supply voltage falls below a preset threshold. In addition, both parts have a debounced manual reset input so that a reset signal can also be initiated with an external switch or logic signal.With six different reset threshold options available ranging from 2.32 V to 4.63 V, the ADM6711 / ADM6713 are suitable for monitoring 2.5 V, 3 V, 3.3 V, and 5 V supplies. A reset timeout of at least 140 ms occurs when VCC rises above the threshold. This gives the supply voltage time to stabilize before the microprocessor starts up.The ADM6711 has a push-pull output, so no additional external components are needed. The ADM6713 open-drain output requires an external pull-up resistor that can be connected to a voltage higher than VCC, if desired.The parts are highly reliable with accurate voltage references and immunity to fast, negative-going transients on VCC. Low current consumption and space-efficient, 4-lead SC70 packaging make the ADM6711 / ADM6713 ideal for use in low power portable applications.APPLICATIONS Microprocessor systems Computers Controllers Intelligent instruments Automotive systems
