1.1 EVM Features

The BQ25960 evaluation module (EVM) is a complete charger module for evaluating the highly-integrated BQ25960 switched cap battery charger in WCSP package for 1-cell Li-Ion and Li-polymer batteries in a wide range of smartphones and tablets.

The BQ25960EVM presents a complete fast charging solution. A typical use case is for the BQ25611D buck charger (U4) to perform pre-charge and charge termination, while one or both of the BQ25960 switched cap chargers (U1 and U2) perform fast charging in order to achieve the highest possible efficiency.

Users can configure the EVM for either single BQ25960 operation or dual BQ25960 operation based on the jumper settings described in the next section. In single BQ25960 operation, only U1 charges the battery. In dual BQ25960 operation, U1 acts as the primary charger, and U2 acts as the secondary charger.

This EVM does not include the EV2400 interface board. To evaluate the EVM, an EV2400 interface board must be ordered separately.

The device data sheet listed in Table 1-1 provides detailed features and operation.
