PRODUCTION DATA
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 Section 7.5). Connecting this pin to a ground referenced capacitor ≥ 100 pF gives a user-programmable delay time. See Section 8.3.2 for more information. |
GND | 2 | 5 | — | Ground |
MR | 3 | 4 | I | Driving the manual reset pin ( MR) low asserts RESET. MR is internally tied to VDD by a 90-kΩ pull-up resistor. |
RESET | 1 | 6 | O | RESET 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 pull-up resistor from 10 kΩ to 1 MΩ should be used on this pin, and allows the reset pin to attain voltages higher than VDD. |
SENSE | 5 | 2 | I | This pin is connected to the voltage to be monitored. If the voltage at this terminal drops below the threshold voltage VIT, then 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. |
