Notes

2. Minimum value of –18 V is guaranteed by design for switch input voltage range (SGx, SPx).

3. ESD testing is performed in accordance AEC Q100, with the Human Body Model (HBM) (CZAP = 100 pF, RZAP = 1500

Ω), the Machine Model (MM) (CZAP = 200 pF, RZAP = 0 Ω), and the Charge Device Model (CDM).

4. CZAP = 330 pF, RZAP = 2.0 kΩ (powered and unpowered) / CZAP = 150 pF, RZAP = 330 Ω (unpowered)

5. External component requirements at system level:

Cbulk = 100 μF aluminum electrolytic capacitor

Cbypass= 100 nF ±37 % ceramic capacitor

Reverse blocking diode from Battery to VBATP (0.6 V < VF < 1 V). See Figure 22, Typical application diagram.
