IP2320概述:
The IP2320 is a boost charge management IC that supports dual series Li-ion batteries.
IP2320 integrates power MOS and adopts synchronous switching architecture, so that it requires few peripheral devices in application, and effectively reduces the overall solution size and BOM cost.
IP2320 boost switch charging converter operating frequency 400KHz; 5V input, 8V/1A output conversion efficiency 92%;
The IP2320 has the input undervoltage protection function, which can intelligently adjust the charging current and adapt the load capacity of the adapter to prevent the adapter from being pulled down.
IP2320 support LED pin resistor set charging current, can set 4 constant current charging current.
The IP2320 supports external resistors to adjust the charging voltage, and the charging voltage can be adjusted continuously.
IP2320 integrated NTC protection function, with 10K NTC resistance to achieve charging NTC protection
The IP2320 is packaged in ESOP8.
