The MAX20342 is a USB Type-C^® charger detector that is also capable of detecting chargers compliant with the USB Battery Charging Specification Revision 1.2. The USB Type-C charger detection circuitry functions as a UFP or DRP depending on factory configuration.

The device implements USB Type-C detection logic and enables systems to support charging based on USB Type-C ports. The device also includes charger detection capability for BC1.2 compatible chargers and detects USB standard downstream ports (SDPs), USB charging downstream ports (CDPs), dedicated charger ports (DCPs), and other proprietary chargers. GPIO outputs allow the MAX20342 to control an external lithium-ion (Li+) battery charger based on charger detection results.

The MAX20342 integrates a resistance detection block that can be used to automatically configure factory configuration states based upon attached resistors. Additionally, the resistance measurement can be configured to detect the presence of moisture in the USB Type-C connector.

The MAX20342 also features an integrated low on-resistance, low-capacitance double-pole double-throw (DPDT) USB switch that can pass Hi-Speed USB, full-speed USB, low-speed USB, and UART signals. The switch position can be automatically configured by the USB detection logic or manually controlled.

The MAX20342 features high-ESD protection up to ±15kV human-body model (HBM) on CC1, CC2, SBU1, and SBU2 pins. The CDP and CDN pins are protected against ESD up to ±6kV. The MAX20342 is specified for ±15kV Air-Gap and ±8kV Contact Discharge IEC 61000-4-2 on the CC1, CC2, SBU1, and SBU2 pins. The MAX20342 is available in a 24-bump, 0.4mm pitch, 2.62mm x 2.02mm wafer-level package (WLP) and operates over the -40°C to +85°C extended temperature range.

Product Details

The MAX20342 evaluation kit (EV kit) is a fully assembled and tested PCB that evaluates the MAX20342 USB Type-C^® charger detector with integrated overvoltage protection. 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. The EV kit ships with jumpers installed and supply voltages set to typical operating values.
