PIN FUNCTION DESCRIPTION
Pin No. Symbol Description
1 I Input; Battery Supply Input Voltage. Bypass to ground with a ceramic capacitor.
2 RO Reset Output; Open Collector Active Reset (accurate when I > 1.0 V).
3 GND Ground; Pin 3 internally connected to tab.
4 D Reset Delay; timing capacitor to GND for Reset Delay function.
5 Q Output; ±2.0%, 450 mA output. 22 F, ESR < 5.0 Ω to ground.

Maximum ratings are those values beyond which device damage can occur. Maximum ratings applied to the device are individual stress limit values
(not normal operating conditions) and are not valid simultaneously. If these limits are exceeded, device functional operation is not implied, damage
may occur and reliability may be affected.
