BQ24250EVM-150 Datasheet PDF - TI

●The BQ24250EVM-150 is an Evaluation Module for evaluate the operation and performance of BQ24250/51/57, a single input I²C/standalone switch-mode Li-Ion battery charger. The BQ2425x series are highly integrated single cell Li-Ion battery chargers targeted for space-limited, portable applications with high capacity batteries. The single cell charger has a single input that operates from either USB port or AC wall adapter for a versatile solution. BC1.2 compliant D+/D detection allows for recognition of CDP, DCP, SDP and non-standard USB adapters. The use of an accessory dead battery provision (DBP) pin allows for the system to sync a dead battery state in order to enable/disable the BC1.2 detection in the case of an external USB-PHI.
