Shenzhen Meiyuxin Technology Co., Ltd. [BOM distribution list] sells TPS7B6833QPWPRQ1 Automotive 500mA, Battery Powered Operation (40V), High PSRR, Low IQ, Low Dropout Voltage Regulator with Watchdog Timer In Stock! ! !

Product Description:

TPS7B6833QPWPRQ1 In automotive microcontroller or microprocessor power supply applications, the watchdog is used to monitor the working status of the microcontroller to prevent software from getting out of control. In a reliable system, the watchdog must be independent of the microcontroller.

The TPS7B6833QPWPRQ1 is a 500-mA watchdog LDO designed for operation up to 40-V with a typical quiescent current of only 19 µA at light load. The device integrates a programmable function to select windowed or standard watchdog and use external resistors to set the watchdog time within 10% accuracy.

The PG pin on the TPS7B6833QPWPRQ1 indicates when the output voltage has reached regulation and is within regulation. The power good delay period and power good threshold can be adjusted by external components. Additionally, the device is short-circuit and overcurrent protected. This combination of features makes the device extremely flexible for powering microcontrollers in automotive applications.
