ADP3405 Overview
The ADP3405 is a multifunction power management system IC optimized for GSM cell phones. The wide input voltage range of 3.0 V to 7.0 V makes the ADP3405 ideal for both single cell Li-Ion and three cell NiMH designs. The current consumption of the ADP3405 has been optimized for maximum battery life, featuring a ground current of only 150 µA when the phone is in standby (digital LDO, and SIM card supply active).
