Multi-chemistry charger with 10 A ceiling
It accepts a supply voltage up to 24 V and supports a maximum battery pack voltage of 18 V.
10 A charge current — sizing the power stage
The 10 A max charge current sets the floor for the external MOSFETs, inductor, and input capacitor. At 10 A continuous, the power dissipation in the pass FET and sense resistor drives the thermal design — the 28-VFQFN exposed pad needs a solid copper pour and vias to the ground plane to keep junction temperature below 125°C. The constant-current programming loop lets the system set the charge rate via an external resistor or DAC, so the same BOM can cover different battery capacities by adjusting the current setpoint.
