Ultra-Low Power PMICs Increase Battery Life and Efficiency for Wearables

Mouser Electronics, Inc., is now stocking MAX77650 and MAX77651 power management ICs (PMICs) from Maxim Integrated. These ultra-small, ultra-low-power PMICs integrate voltage regulators with a charger and current regulators to reduce external component count when designing small lithium-ion battery-operated products.

Maxim’s MAX77650 and MAX77651 PMICs, available from Mouser, offer a flexible and configurable power management solution in a compact total size of 28 × 28 mm. The devices achieve the small size through a single-inductor, multiple-output (SIMO) buck-boost regulator that offers three independently programmable power rails. For design flexibility, the MAX77650 operates up to 3.3V and the MAX77651 operates up to 5V. Both products include an analog multiplexer output for safe battery monitoring, making them ideal for low-power designs.

The devices offer a standby current of just 0.3 µA and an operating current of only 5.6 µA when all three SIMO channels and the low dropout (LDO) regulator are enabled. The devices’ wide array of programmable options makes them ideal for many battery-powered devices, such as Bluetooth-enabled headsets, fitness monitors, portable devices and Internet of Things (IoT) nodes.
