ADVANCE DATASHEET SGM41664 Efficient I2C Power Backup Manager with High Current Bidirectional DC/DC Converter and Capacitor Measurement Capability GENERAL DESCRIPTION The SGM41664 is a programmable power management IC with I2C interface and integrated analog-to-digital converter (ADC) for applications that need backup power or energy storage capability such as solid-state drivers (SSD). For example, in an SSD the power is needed for a few milliseconds after an unexpected supply loss to complete any remaining write action. The integrated efficient bidirectional synchronous buck converter/boost charger is capable of charging storage capacitors to as high as 36V from a 2.6V to 16V input source.
