The MAX14690 is a battery-charge-management solution ideal for low-power wearable applications. The device includes a linear battery charger with a smart power selector and several power-optimized peripherals. The MAX14690 features two ultra-low-power buck regulators with a typical quiescent current of 900nA. In addition, three ultra-low power low-dropout (LDO) linear regulators, with a typical quiescent current of 600nA are included. In total, the MAX14690 can provide up to five regulated voltages, each with an ultra-low quiescent current, critical to battery life for the unique power profile in 24/7 operation devices, such as those in the wearable market.
