Pin Functions

PIN I/O DESCRIPTION
NAME TPS3820‑xx‑Q1,
TPS3823‑xx‑Q1,
TPS3828‑xx‑Q1		 TPS3824‑xx‑Q1 TPS3825‑xx‑Q1
GND 2 2 2 — Ground connection
MR 3 — 4 I Manual-reset input. Pull low to force a reset. RESET remains low as long as MR is low and for the time-out period after MR goes high. Leave unconnected or connect to VDD when unused.
RESET — 3 3 O Active-high reset output. Either push-pull or open-drain output stage.
RESET 1 1 1 O Active-low reset output. Either push-pull or open-drain output stage.
VDD 5 5 5 I Supply voltage. Powers the device and monitors its own voltage.
WDI 4 4 — I Watchdog timer input. If WDI remains high or low longer than the time-out period, then reset is triggered. The timer clears when reset is asserted or when WDI sees a rising edge or a falling edge. If unused, the WDI connection must be high impedance to prevent it from causing a reset event.
