Texas Instruments BQ24800 | Demoboard BQ24800EVM
SMBus 2-S to 4-S hybrid power boost mode battery charge controller evaluation module
Overview
| Topology | Battery Management System |
| Input voltage | 18-24 V |
| Output 1 | 19.2 V / 8 A |
Description
The BQ24800 evaluation module (EVM) is an SMBus 1- to 4-cell hybrid power boost mode battery charge controller with battery-only boost and processor hot monitoring. The input voltage range is between 4.5 V and 24 V, with a programmable output of 1–4 cells charge voltage and 128-mA to 8.128-A charge current. This EVM does not include the EV2400 interface device; it must be ordered separately to evaluate the BQ24800 EVM.
Features
- Host-controlled 2-S to 4-S battery buck charger with 3.2-V to 24-V input; 1-V to 19.2-V charging output
- Hybrid power boost mode to provide system power from adapter and battery simultaneously
- Peak power mode to optimize adapter utilization without discharging battery
- Battery-only boost mode to extend battery usable range
Typical applications
- medical equipment
- Notebook, ultrabook, detachable, and tablet PC
- Portable equipment
- System with battery backup, Industrial
