STM1404

Description

9/36

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 µF.

3.

Open drain

4.

Diode is required for battery reverse charge protection.

5.

VREF only for STM1404A; VTPU for STM1404B/C
