Maxim Integrated MAX20342 USB Type-C® Charger Detector

Maxim Integrated MAX20342 USB Type-C® Charger Detector enables systems to support charging based on USB Type-C ports. The MAX20342 is also capable of detecting chargers compliant with the USB Battery Charging Specification Revision 1.2. The device 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 high-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 electrostatic discharge (ESD) protection up to ±15kV human-body model (HBM) on the CC1, CC2, SBU1, and SBU2 pins. The CDP and CDN pins are protected against ESD up to ±6kV. The device is specified for ±15kV Air-Gap and ±8kV Contact Discharge IEC 61000-4-2 on the CC1, CC2, SBU1, and SBU2 pins. The Maxim Integrated MAX20342 USB Type-C Charger Detector is available in a 2.62mm x 2.02mm, 24-bump Wafer-Level Package (WLP) and operates over the -40ºC to +85ºC extended temperature range.
