Description
AI
In automotive microcontroller or microprocessor power-supply applications, the watchdog is used to monitor the microcontroller working status to prevent software runaway. The watchdog must be independent of the microcontroller in a reliable system.
The TPS7B63xx-Q1 is a family of 300-mA watchdog low-dropout regulators (LDOs) designed for an operating voltage up to 40 V, with typical quiescent current of only 19 µA at light load. The devices integrate a programmable function for selecting a window watchdog or standard watchdog, with an external resistor to set the watchdog time within 10% accuracy.
The PG pin on the TPS7B63xx-Q1 devices indicate when the output voltage is stable and in regulation. The power-good delay period and power-good threshold can be adjusted by selecting external components. The devices also feature integrated short-circuit and overcurrent protection. The combination of such features makes these devices particularly flexible and suitable to supply microcontroller in automotive applications.
