1 Introduction

The TPS7H3014-SEP is an integrated 3V to 14V, four channel radiation-hardness assured power-supply sequencer. The channel count can be incremented as needed for the application by connecting multiple ICs in a daisy-chain configuration. The device features sequence up and reverse sequence down control signals (UP and DOWN), SEQ-DONE and PWRGD flags to monitor the sequence and power status of the monitored power tree. Other features for the device include:

  • A 599mV ± 1% threshold voltage
  • 24µA ± 3% hysteresis current
  • Common programmable (268µs to 23.37ms) delay timer
    • Valid during sequence up and down
  • Time-to-regulation programmable timer (264µs to 23.63ms) to track rising voltage on SENSEX
    • Valid only during sequence up
  • Open drain FAULT detection pin to monitor internally generated faults

The device is offered in a 24-pin plastic (TSSOP) package. General device information and test conditions are listed in Table 1-1. For more detailed technical specifications, user-guides, and application notes please go to TPS7H3014-SEP product page.
