Consumer gear, like Bluetooth headphones, activity monitors, smart garments, and smartwatches, can increase their battery life and efficiency thanks to the MAX77650/651 power management ICs (PMICs), developed by Maxim Integrated Products.
Many PMICs for these small, lithium-ion battery-operated devices require additional components, such as boost, buck, and low-dropout (LDO) regulators; a charger; or current regulators for LED indicators. The MAX77650/651 integrates all these functions into one complete power solution that measures just 19.2 mm2.
The MAX77650 and MAX77651 feature single-inductor, multiple-output (SIMO) buck-boost regulators that provide three independently programmable power rails from one inductor, a 150-mA LDO, and three current sink drivers. The MAX77650 operates at up to 3.3 V and the MAX77651 operates at up to 5 V. Both parts include an analog multiplexer (MUX) output for safe battery monitoring.
Both parts are available from stock and sell for $1.99 in lots of 1000. Eval kits for both are also available for $193.63.
