The TP4333 from TPOWER is an integrated power management IC designed for mobile power applications. It combines charge management, synchronous boost (discharge) control, status indication, and multiple safety features in a single SOP-8 package. It’s ideal for power banks and other systems that require efficient 5V output, battery charging, and protection in a single chip.
Features
- Discharge (boost) output: 5V / 1A
- Charge current fixed at 0.8A
- Boost (output) efficiency up to ≈ 93%
- BAT discharge termination voltage: 2.85V
- Optional full charge voltage: 4.2V or 4.35V
- Temperature feedback control (e.g. over-temperature protection, reduces current when chip's internal temp ~120 °C)
- Trickle charge mode when battery voltage is low (before ~2.9V)
- Load detection and auto low-power standby when no load present after delay (~18s)
- LED indication: charging, discharging, low battery alarms etc.
- Flashlight output support (LED drive) via a switch pin; max ~50 mA drive current
Applications
- Power bank / portable charger designs
- Battery-powered mobile devices
- Sustainable 5V USB output modules
- Systems needing integrated protection (overcharge, overdischarge, short-circuit)
- Emergency flashlight / LED indicator functions
