FS5502

High voltage PMIC with multiple SMPS and LDO

22 Electrostatic discharge

22.1 Human body model (JESD22/A114)

The device is protected up to ±2 kV, according to the human body model standard with

100 pF and 1.5 kΩ. This protection is ensured at all pins.

22.2 Charged device model

• The device is protected up to ±500 V, according to AEC-Q100 - 011 charged device

model standard. This protection is ensured at all pins.

22.3 Discharged contact test

The device is protected up to ±8 kV, according to the following discharged contact tests.

Discharged contact test (IEC61000-4-2) at 150 pF and 330 Ω

Discharged contact test (ISO10605.2008) at 150 pF and 2 kΩ

Discharged contact test (ISO10605.2008) at 330 pF and 2 kΩ

This protection is ensured at VSUP1, VSUP2, WAKE1, WAKE2 pins.

Assumptions

LPI_DCR = 30 mΩ

DMAX = 98.18 % with FPRE_SW = 455 kHz and TPRE_OFF_MIN = 40 ns

IPRE = 3.0 A

VRBD = 0.56 V

VBAT_MIN = 3.4 V when VPRE = VPRE_UVL

Figure 29. Operating range

• Below VSUP_UVH threshold, the extended operation range depends on VPRE output

voltage configuration and external components.

– When VPRE is configured at 5.0 V, VPRE may not remain in its regulation range

– VSUP minimum voltage depends on external components (LPI_DCR) and application

conditions (IPRE, FPRE_SW)

• The FS5502 maximum continuous operating voltage is 36 V when VPRE is switching at

455 kHz.

• The FS5502 maximum continuous operating voltage is 36 V when VPRE is switching

at 455 kHz. It has been validated at 48 V for limited duration of 15 minutes at room

temperature to satisfy the jump-start requirement of 24 V applications. It can sustain 58

V load dump without external protection.

• When VPRE is switching at 2.2 MHz, the FS5502 maximum continuous operating

voltage is 18 V. It is validated at 26 V for limited duration of 2 minutes at room
