The Maxim MAX77734 PMIC from MOZE is a user-configurable, flexible power management solution with a chip size of only 2.23 × 1.97 mm. The PMIC integrates a linear Li-Ion battery charger, a low dropout (LDO) linear regulator, analog multiplexer Consumer and dual-channel sink drivers reduce the number of external components when designing small-size battery-powered products.
Chargers are specifically designed for small battery systems with terminal currents as low as 0.375 mA Chargers 3.6 V to 4.6 V programmable battery regulation range to support batteries of various chemistries When connected to an input source, Depleted and the circuitry can also immediately adjust the system voltage The output of the 150 mA LDO regulator can be adjusted via I2C between 0.8 V and 3.975 V while the analog multiplexer allows the external analog-to-digital converter ADC) is able to perform battery voltage and current signal conversions for power monitoring Each channel has a sink current of 12.8 mA and can be set by the user to flash the LED in a customized mode.
The MAX77734 PMIC features a standby current of only 1.5 μA and a quiescent current of only 4.5 μA with the LDO regulator enabled. The device's extensive programmable options make it suitable for use with a wide range of battery-operated devices such as Bluetooth® headsets, body monitors, Wearable cameras and low-power Internet of Things (IoT) devices.
The MAX77734 PMIC has its own MAX77734 evaluation kit that engineers can use to test linear charger, voltage regulator, multiplexer, and interface features through the Windows GUI.
