The LTC4160 is a versatile, high efficiency power manager and battery charger that incorporates a bidirectional switching regulator, full featured battery charger, an ideal diode (with a controller for an optional external ideal diode), and an optional overvoltage protection circuit.
The LTC4160 is a versatile high-efficiency power manager that incorporates a bidirectional switching regulator, a full-featured battery charger, an ideal diode controller, and optional overvoltage protection. It enables efficient charging and automatic USB On-The-Go functionality using a single inductor.
Key features include the ability to power a portable system or charge its battery from a 5V input, and provide a 5V output for USB On-The-Go when powered by a battery. The device supports automatic detection of micro-AB cable orientation via the ID pin.
The programmable charge current has a maximum of 1.2A.
In USB On-The-Go mode, the regulator is capable of delivering at least 500mA.
The circuit can provide protection up to 68V on the VBUS pin.
