Description
Figure 4.
Hardware hookup
1.
Normal mode: low when VOUT is internally switched to VCC and high when VOUT is internally switched to
battery.
2.
Capacitor (C) is typically
≥ 10 F.
3.
Open drain
4.
Diode is required for battery reverse charge protection.
5.
VREF only for STM1404A; VTPU for STM1404B/C
