MAX77734CENP+ by Analog Devices

Ultra-Low Power Tiny PMIC with Power Path Charger for Small Li+ and 150mA LDO


The MAX77734 is a tiny PMIC for applications where size and simplicity are critical. The IC integrates a linear-mode Li+ battery charger, low-dropout linear regulator (LDO), analog multiplexer, and dual-channel current sink driver. The charger is designed for small-battery systems that require accurate termination as low as 0.375mA. The circuit can instantly regulate the system voltage when an input source is connected even if the battery is depleted. The 150mA LDO's output is programmable between 0.8V and 3.975V with I²C. The analog MUX enables an external ADC to perform conversions on battery V&I signals for power monitoring. The current sinks are capable of sinking 12.8mA each and can be programmed for LEDs to blink in custom patterns. The MAX77734 is available in a 20-bump, 0.4mm pitch wafer-level package (WLP). For a similar product with additional regulators, see the MAX77650. Design Solution: Can You Hear Me Now? Extend the Life of Your Hearable Device ›
