Pin Description—MAX16020/MAX16021 (continued)
Active-Low Watchdog Output. WDO asserts when WDI remains high or low longer than the
watchdog timeout period. WDO returns high on the next WDI transition or when a reset is
asserted.
Active-Low Power-Fail Comparator Output. PFO goes low when V

Active-Low Reset Output. RESET asserts when V
pulled low. RESET remains low for the duration of the reset timeout period after V
above the reset threshold and MR goes high.
Switched Output. OUT is connected to V

Active-Low Chip-Enable Output. CEOUT goes low only when CEIN is low and reset is not
asserted. If CEIN is low when reset is asserted, CEOUT stays low for 12µs (typ) or until
CEIN goes high, whichever occurs first.
Chip-Enable Input. The input to CE gating circuitry. Connect to GND or OUT if not used.
Supply Voltage Input. Bypass V
Exposed Pad. Internally connected to GND. Connect EP to a large ground plane to aid
heat dissipation. Do not use EP as the only ground connection for the device.
