Pin Functions

PIN I/O DESCRIPTION
NAME SOT-23 WSON
CT 4 3 I Reset period programming pin. Connecting this pin to VDD through a 40-kΩ to 200-kΩ resistor or leaving it open results in fixed delay times (see Electrical Characteristics). Connecting this pin to a ground referenced capacitor ≥ 100 pF gives user-programmable delay time. See the Selecting the Reset Delay Time for more information.
GND 2 5 — Ground
MR 3 4 I Manual reset. Driving this pin low asserts RESET. MR is internally tied to VDD by a 90-kΩ pullup resistor.
RESET 1 6 O Reset. This is an open-drain output that is driven to a low impedance state when RESET is asserted (either the SENSE input is lower than the threshold voltage (VIT) or the MR pin is set to a logic low). RESET remains low (asserted) for the reset period after both SENSE is above VIT and MR is set to a logic high. A pullup resistor from 10 kΩ to 1 MΩ must be used on this pin and allows the reset pin to attain voltages higher than VDD.
SENSE 5 2 I Voltage sense. This pin is connected to the voltage to be monitored. If the voltage at this terminal drops below the threshold voltage (VIT), RESET is asserted.
VDD 6 1 I Supply voltage. It is good analog design practice to place a 0.1-μF ceramic capacitor close to this pin.
Thermal Pad — Pad — Thermal pad; connect to ground plan to enhance thermal performance of the package.
