Product Overview

The LTC2924IGN#PBF is a quad 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. An internally regulated charge pump provides gate drive voltages for external logic and sub-logic-level MOSFETs. Adding a single capacitor enables an adjustable time delay between power supplies during both Power On and power-off sequencing. A second capacitor can be added to enable a power good timer for detecting the failure of any power supply to turn-on within the selected time. Errors in power supply sequencing and the control input are detected and reported at the FAULT output.
  • 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
  • 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
  • 10µA Output current allows soft-starting of supplies
