Overview

LTC2924 Quad Power Supply Sequencer www.DataSheet4U.com ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ Fully Sequence and Monitor Four Supplies – Six with Minimal External Circuitry Cascadable for Additional Supplies Power Off in Reverse Order or Simultaneously Charge Pump Drives External MOSFETs Drives Power Supply Shutdown Pins with No External Pull-Up Resistors 10µA Output Current Allows Soft-Starting of Supplies Done Indicator for Both Power On and Power Off Adjustable Time Delay Between Power Supplies Power Good Timer Power Supply Voltage Monitoring and Power Sequence Error Detection and Reporting Available in a 16-Lead Narrow SSOP Package The LTC®2924 is a power supply sequencer designed for use with external N-channel MOSFETs or power supplies with shutdown pins.

Four power supplies can be fully sequenced by a single LTC2924 and up to five supplies can be sequenced to a sixth master supply.

The LTC2924 requires a minimum of external components, using only two feedback resistors per sequenced power supply and a single resistor to set hysteresis.

Key Features

  • precision input comparators which can provide 1% accuracy in monitoring power supply voltages. Multiple LTC2924s may be easily cascaded to sequence a virtually unlimited number of power supplies. , LTC and LT are registered trademarks of Linear Technology Corporation.
