Product Overview
MAX38889AATE+ is a 3A reversible buck/boost regulator for backup applications. It is a flexible storage capacitor or capacitor bank backup regulator transferring power efficiently between a storage element and a system supply rail. The external pins allow various settings such as maximum supercapacitor voltage, system backup voltage (VSYS), and peak inductor charge and discharge current. It implements a True Shutdown™ feature, disconnecting SYS from CAP as well as protecting against a SYS short if VCAP > VSYS. Charging and backup can be disabled by keeping the ENC and ENB pins low, respectively. The backup system status can be monitored through two status outputs: the RDY flag that indicates when the supercapacitor is charged and the BKB flag that indicates when backup operation is occurring. Typical applications are handheld industrial equipment, portable devices/computers with removable battery, industrial sensor and actuators, aftermarket automotive tracking.
- 2.5V to 5.5V system output voltage range
- 0.5V to 5.5V supercapacitor voltage range
- ±1% threshold accuracy
- 2.5% hysteresis between backup and charging
- 94% peak efficiency, charging or discharging mode
- 4µA quiescent current in ready state
- After supercapacitor is charged, draws only 4µA of quiescent current
- Ready and backup state outputs, RDY and BKB flags provide real-time status to system
- Enable input, selectable voltages and currents
- 16-pin TQFN package, -40°C to +125°C temperature range
