The TPS7H3xx4-SP is an integrated, 3V to 14V, four-channel radiation-hardened power-supply supervisor with watchdog. An accurate 599.7mV ± 1% threshold voltage and a 24µA ± 3% hysteresis current provide programmable monitoring voltages. A global programmable delay timer is programmed via a single resistor. Additionally, a PWRGD output is provided to monitor the global power tree status. The device also incorporates a positive edge detection watchdog timer to monitor an external processor for coherent execution. Faults can be detected and mitigated by the external controller, using the SR_UVLO input. The device is offered with push-pull and open-drain outputs types.
