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
not monitored.
Ground (V
This pin (GND) is the ground pin for the power supply and is tied to V
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.
