Maxim has come up with small PMICs for Bluetooth headphones, activity monitors, smart garments, smartwatches, and other size-constrained devices.
The MAX77650 / MAX77651 PMICs do not require additional components such as boost, buck, and low dropout (LDO) regulators, a charger and current regulators for LED indicators. Maxim has integrated all these functions into a 19.2mm-squared device.
The MAX77650 and MAX77651 feature single inductor multiple output (SIMO) buck-boost regulators that provide three independently programmable power rails from a single inductor, 150mA LDO, and three current sink drivers to reduce overall component count and maximize available board space.
For design flexibility, the MAX77650 operates up to 3.3V and the MAX77651 operates up to 5V – both include an analog multiplexer (MUX) output for safe battery monitoring, making them suitable for low-power designs.
Key Advantages
Lowest Standby Power: 0.3µA; 5.6µA operating current
High Efficiency: 3-output SIMO channels plus LDO extend Li+ battery life
Smallest Solution Size: Multi-channel SIMO regulator reduces component count
