TCS6175
USB-Compliant Single-Cell Li-lon Switching Charger with USB-OTG boost Regulator
产品描述
TCS6175 is a switch-mode charging IC with maximum 1.75A current for lithium battery and lithium polymer battery. The TCS6175 has 5V, 700mA OTG function, and I2C function. The charging parameter such as charging current, full charging voltage and input current can be precisely configured by I2C function. The package type is WLCSP (1.901mmx1.501mm)with 20 pins.
The TCS6175 is designed with standard four-stage charging process: active, pre-charging, constant current, constant voltage and perfect protection mechanism for over current, over voltage, under voltage and over temperature.
It is integrated with synchronous PWM control, high power MOSFET, and high voltage OVP circuits. The TCS6175 has high charging efficiency (94%), low internal resistance (45mΩ), and high DC withstand voltage (29V).
