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.

TPS7H3034EVM-CVAL — TPS7H3034-SP 评估模块

TPS7H3024EVM-CVAL、TPS7H3124EVM-CVAL、TPS7H3034EVM-CVAL 和 TPS7H3134EVM-CVAL 演示了单个 TPS7H3024-SP、TPS7H3124-SP、TPS7H3034-SP 或 TPS7H3134-SP 监控器（陶瓷封装）的运行情况。这些电路板布局相同，但 BOM 略有差异，只要更新了已组装的 IC 的配置，就可以互换使用。这些电路板统称为 TPS7H3xx4EVM-CVAL。
