The LTC4221 is a 2-channel Hot Swap™ controller that allows a board to be safely inserted and removed from a live backplane. Using two independent high side gate drivers to control two external N-channel pass transistors, the output voltages can be ramped up with current foldback to limit the inrush current during the start-up period. No external compensation capacitors are required at the GATE pins. The two channels can be configured to ramp up and down separately or simultaneously for supply voltages ranging from 2.7V to 13.5V and 1V to 13.5V for channels 1 and 2 respectively.Each channel has two current limit comparators that provide dual level and dual speed overcurrent circuit breaker protection after the start-up period. If any current sense voltage exceeds 100mV for 1µs or 25mV for the timeout delay (set by the CFILTER at the FILTER pin), then the FAULT latch is set and both GATE pins are pulled low.The FB pins monitor the respective channel output voltages and provide the inputs for the PWRGD comparators as well as overvoltage protection.Applications Electronic Circuit Breaker Power Supply Sequencing Live Board Insertion and Removal Industrial High Side Switch/Circuit Breaker

The LTC4057 is a constant-current/constant-voltage linearcharger for single-cell lithium-ion batteries. ItsThinSOT™ package and low external component countmake the LTC4057 especially well suited for portableapplications. Furthermore, the LTC4057 is specificallydesigned to work within USB power specifications.No external sense resistor is needed and no blocking diodeis required due to the internal MOSFET architecture.Thermal feedback prevents overheating by regulating thecharge current to limit the die temperature during highpower operation or high ambient temperature conditions.The charge voltage is preset at 4.2V and the charge currentcan be programmed externally with a single resistor.When the input supply (wall adapter or USB supply) isremoved, the LTC4057 automatically enters a low currentstate, dropping the battery drain current to less than 2µA.With power applied, the LTC4057 can be put into shutdownmode, reducing the supply current to 25µA.For the standalone version (on-board charge termination)of the LTC4057, refer to the LTC4054.Applications Wireless PDAs Cellular Phones Portable Electronics

The LTC4150 measures battery depletion and charging in handheld PC and portable product applications. The device monitors current through an external sense resistor between the battery’s positive terminal and the battery’s load or charger. A voltage-to-frequency converter transforms the current sense voltage into a series of output pulses at the interrupt pin. These pulses correspond to a fixed quantity of charge flowing into or out of the battery. The part also indicates charge polarity as the battery is depleted or charged. The LTC4150 is intended for 1-cell or 2-cell Li-Ion and 3-cell to 6-cell NiCd or NiMH applications.Applications Battery Chargers Palmtop Computers and PDAs Cellular Telephones and Wireless Modems
