Nano IQ Precision Voltage Supervisor with Precision Timeout Watchdog Timer for Automotive Applications

SGM856xQ.PDF

The SGM856xQ is a high-precision voltage supervisor with ±1.2% accuracy over the operating temperature range. It only consumes 750nA (TYP) quiescent current and provides a timeout watchdog with fixed timeout period.

The SGM856xQ gives four available watchdog timeout period options, which are preset as a default value and can be configured by the users for setting different multiples of the default value by SET0/SET1. The watchdog function can be enabled or disabled by the WD_EN pin.

The output asserted times for nRESET or nWDO are all preset. The SGM856xxD-xQ is a unique device that latches the output until an effective watchdog input is detected.

The device is AEC-Q100 qualified (Automotive Electronics Council (AEC) standard Q100 Grade 1) and it is suitable for automotive applications.

The SGM856xQ is available in a Green TSOT-23-8 package.
