Maxim Integrated MAX20342 USB Type-C Charger Detector, available now from Mouser, allows systems to support charging based on USB Type-C ports. The device is also able to detect chargers compliant with the USB Battery Charging Specification Revision 1.2. The device detects USB SDPs, USB CDPs, DCPs, and other proprietary chargers. GPIO outputs enable the detector to control an external lithium-ion (Li+) battery charger based on charger detection results.
The device combines a resistance detection block that can be utilised to automatically configure factory configuration states based on attached resistors. Furthermore, the resistance measurement can be set to detect the presence of moisture in the connector.
The detector also provides an integrated low on-resistance, low-capacitance DPDT USB switch that can pass high-speed USB, full-speed USB, low-speed USB, and UART signals. The switch position can be automatically set by the USB detection logic or manually controlled.
The device offers high ESD protection up to ±15kV HBM on the CC1, CC2, SBU1, and SBU2 pins. The CDP and CDN pins are shielded 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.
This USB Type-C Charger Detector is offered in a 2.62mm x 2.02mm, 24-bump WLP and operates over the -40C to +85C extended temperature range.
