PMICs from Maxim result in smaller consumer devices
July 26, 2017
PMICs from Maxim save board space and increase efficiency.
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.
