The separate VDD and SENSE pins allow for the redundancy sought by high-reliability systems. SENSE is decoupled from VDD and can monitor rail voltages other than VDD. Optional use of external resistors are supported by the high impedance input of the SENSE pin. Both CTS and CTR provide delay adjustability on the rising and falling edges of the RESET signals. CTS also functions as a debouncer by ignoring voltage glitches on the monitored voltage rails and operates as a "manual reset" that can be used to force a system reset.

The precision performance, best in-class features in a compact form factor, makes the TPS3899-Q1 an ideal solution for wide ranging automotive and battery-powered / low-power applications. The device is fully specified over a temperature range of –40°C to +125°C (TA).
