Description

The TPV803/809/810 is a series of supervisory circuit

that monitors power supply voltage levels and provides a

power-on reset signal. They provide a reset output during

power-up, power-down, and brownout conditions.

The reset timeout periods are fixed at 200 ms (typical).

The TPV803 and TPV809 provide an active low reset

signal (RESET), whereas the TPV810 provides an active

high signal (RESET) output. The TPV809 and TPV810

have push-pull outputs, whereas the TPV803 has an opendrain output, which requires an external pull-up resistor.

The TPV803/809/810 is available in SOT23-3 and

SOT23G-3 packages and typically consumes only 2.2 μA,

suitable for use in low-power, portable applications.
