MAX8814ETA+T

The MAX8814ETA+T is a linear Li+ battery charger with autoboot assistant in 8 pin TDFN package. It is an intelligent, stand-alone constant-current, constant-voltage (CCCV), thermally regulated linear charger which is designed for charging a single-cell lithium-ion (Li+) battery. The device controls the charging sequence from the prequalification state through constant-current fast-charge and the final constant voltage charge. MAX8814 achieves high flexibility by providing an adjustable fast-charge current through an external resistor. It also features a booting assistant circuit that distinguishes input sources, battery connection and provides an output signal (ABO) for system booting.

• Integrated current-sensing circuit, MOSFET pass element and thermal regulation circuitry
• 4.25V to 28V input voltage range with over-voltage protection above +7V
• Soft-start limits inrush current
• Programmable fast-charge current of 1A (max)
• Charge-current monitor for fuel gauging (ISET)
• Input power-source detection output and charge-enable input
• Low dropout voltage (300mV at 500mA)
• Operating temperature range from -40°C to 85°C
