Datasheet Summary
Nano Power Buck-Boost with Input Voltage Monitor
General Description
The MAX77887 is a high-efficiency nano power buckboost converter with an input voltage monitoring feature, ensuring that the battery voltage does not drop below the pre-set threshold levels to protect the battery.
The converter operates on an input supply between 1.8V and 5.5V. Output voltage between 1.8V and 5.2V is configured through a resistor connected to the hardware control pin, RSEL1. It can operate in CCM, Skip, and Low Power Mode to ensure maximum efficiency over a wide range of load currents.
MAX77887 offers two unique hardware control pins RSEL1 and RSEL2. The resistor connected at SEL1 (RSEL1)...
