WQFN-FCRLF (RAV)-24-12 mm² 4 x 3
3mm × 4mm 25-pin package with wettable flank
The TPS61382Q1 is 400kHz, 40V, 15A automotive bi-directional boost converter/ buck charger with battery state of health detection function for back-up power like TBOX. The converter supports absmax voltage up to 40V on VOUT pin to withstand load-dump and supports connecting to 12V car battery.
The TPS61382Q1 integrates I2C configurable buck/LDO charger supporting NiMH, Li-Ion, LiFePO4, super capacitor.
TPS61382Q1 integrates boost function that operates over 0.5V to 3.8V BUB voltage and 5-12V output voltage. The device applies fix frequency peak current control scheme with optional spread spectrum to minimize EMI. The boost function supports 5A-15A programmable average current limit.
The TPS61382Q1 integrates battery health detection feature which discharges the battery with a constant current and detects the voltage drop across the battery internal resistance.
The TPS61382Q1 is available in a 3mm × 4mm QFN package with wettable flank. Care needs to be taken when designing the PCB with TPS61382Q1, view for details.
