Description
- PMP9668.4, Universal uP Controlled Battery Charger of 24 Vin, 10 A out max, 5/12V at 2A/5V at 4A, 2 USB Ports Reference Design. The BQ24745 is a host controlled synchronous buck battery charger capable of charging batteries at up to 19.2V and up to 8A normally, extended to 10 A with use of 8 m-Ohm battery sense resistor. The power train is capable of 8A with convection only cooling and 10A with moderate fan cooling (200 LFM). The Test Report includes thermal images for both cases. While the design shows a 28 pin MSP430 as the host, any processor with SMBUs capability will work. A5/12V 2A auxiliary converter using TPS54335 and 5V at 4A with TPS40170 with 2x CSD18504 are provided. for the two USB ports, the design provides TPS2561A for power switching and TPS2513A for control. A linear TPS70933 provides the 3.3V for the MSP430 and interface signals
