9 / 34 page  STM1403 Description 9/35 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 STM1403; VTPU for STM1403B/C. Figure 5. Tamper pin (TP1 or TP3) normally high (NH) external hookup (switch closed) 1. R typical is 10 M Ω. Resistors must be protected against conductive materials.
