The MAX20332 is a USB charger detector compliant with USB Battery Charging Specification Revision 1.2. The USB charger detection circuitry detects USB standard downstream ports (SDPs), USB charging downstream ports (CDPs), or dedicated charger ports (DCPs), and controls an external lithium-ion (Li+) battery charger.

The device implements USB Battery Charging Specification Revision 1.2-compliant detection logic. The device also includes Apple® charger detection that allows identification of resistor-divider networks on D+/D-.

The internal double-pole double-throw (DPDT) USB switch is compliant to Hi-Speed USB, full-speed USB, low-speed USB, and UART signals. The device’s internal switch features low on-resistance, low on-resistance flatness, and very low capacitance. The ID pin controls the DPDT switch position. The MAX20332 features high-ESD protection up to ±15kV Human Body Model (HBM)on CD+, CD-, and ID pins.

The MAX20332 is available in a 16-bump, 0.4mm pitch, 1.8mm x 1.9mm wafer-level package (WLP) and operates over the -40°C to +85°C extended temperature range.

Product Details

The MAX20332 evaluation kit (EV kit) is a fully assembled and tested PCB that evaluates the MAX20332 USB charger detection with integrated overvoltage protector. The EV kit features a Pmod™ connector, allowing the USB2PMB2 adapter board to provide I²C interface.

The EV kit features an on-board LDO to generate a supply voltage from the USB +5V. The on-board LDO output is configurable for 4.2V, 3.3V, or 2.3V to power the IC.

The EV kit software controls the USB2PMB2 adapter board over the USB, which generates I²C commands.
