Pin descriptions
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 V
CC
power supply but is
not monitored.
Ground (V
SS
)
This pin (GND) is the ground pin for the power supply and is tied to V
SS
.
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.

1. The STM6700 and STM6710Q are powered via the V2IN input which is the supply voltage. When this pin is
V
CC
, the input is not monitored.
