Description

The MAX14656 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 MAX14656 features high-ESD protection up to ±15kV Human Body Model (HBM) on CD+, CD-, and ID pins.

The MAX14656 is available in a 16-bump, 0.4mm pitch, 1.8mm x 1.9mm WLP package and operates over the -40°C to +85°C extended temperature range.
