Description

The TPS61381-Q1 is 400kHz, 40V, 15A automotive bi-directional boost converter/ LDO charger with battery state of health detection function designed for back-up power systems like TBOX or e-call. The converter supports absmax voltage up to 40V on VOUT pin to withstand load-dump condition and supports direct connection with 12V car battery.

The TPS61381-Q1 integrates I2C configurable LDO charger supporting NiMH, Li-Ion, LiFePO4, super capacitor.

TPS61381-Q1 integrates boost function that operates over 0.5V to 12V 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 TPS61381-Q1 integrates battery health detection feature which discharge the battery with a constant current and detects the voltage drop across the battery internal resistance.

The TPS61381-Q1 is available in a 3mm × 4mm QFN package with wettable flank. Care must be taken when designing the PCB with TPS61381-Q1, view for details.
