DESCRIPTION

The TPS3807 family microprocessor supervisory

circuits monitor system voltages as low as 1.225V.

These devices assert an open-drain RSTVDD signal

when the VDD voltage drops below a preset threshold. The RSTVDD output remains asserted

until the VDD voltage returns above its threshold. The

device also provides an additional RSTSENSE

output for a SENSE input with adjustable thresholds

and hysteresis.

The TPS3807 uses a precision reference to achieve

1% threshold accuracy. The TPS3807 has a very low

typical quiescent current of 3.5mA, so it is well-suited

to battery-powered applications. It is available in a

small SC70-5 package, which is half the size of a

SOT-23 package, and is fully specified over a

temperature range of –40°C to +85°C.
