MAX14578AEETE+

MAXIM INTEGRATED PRODUCTS MAX14578AEETE+ Battery Li-Ion Charger Detector IC, USB Interface, 1 Cell, 2.8V to 5.5V supply, TQFN-16

The is an USB battery charger detector in 16 pin TQFN package. 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 implement USB battery charging revision1.1-compliant detection logic including data contact detection, D+/D- short detection, charging downstream port identification. The MAX14578AE features an enable input and an LDO output. The internal USB switch is compliant to Hi-Speed USB, full-speed USB and low-speed USB signals. The device feature low on-resistance, low on-resistance flatness and very low capacitance. The device also features high-ESD protection up to ±15KV human body model on the CD+ and CD- pins. In addition, the device feature Apple and Sony charger detection that allows identification of resistor-divider networks on D+/D-.
