1. Open drain

2. For the STM6700 and STM6710Q, pin 2 is a fixed VCC, thereby making it a triple voltage reset, while the

STM6710 is a quad voltage reset.

V1IN, V3IN,V4IN (VxIN)

The VxIN pins are used for nominal input voltages for 1.8 V, 2.5 V and 5.0 V supplies. The

voltage at this pin is compared against an internal factory-programmed voltage trip point,

Vrst.

RESET is first asserted low when the device is initially powered and VxIN < 1 V and then at

any time thereafter when VxIN falls below Vrst. The device is designed with typical

hysteresis of 0.3 % with respect to its threshold to help prevent oscillation due to noise and

is immune to brief power supply transients.

V2IN

The V2IN is used to power the STM6710 device. In normal operations V2IN is also

monitored. For STM6710Q and STM6700 variations this pin is the VCC power supply but is

not monitored.

Ground (VSS)

This pin (GND) is the ground pin for the power supply and is tied to VSS.

RESET

The RESET output is an open drain output that asserts low whenever a monitored supply

falls below the minimum threshold. STM6710 provides an extended reset timeout period of

typically 200 ms.
