The TPS61383-Q1 is a 400kHz, 40V, 30A automotive bi-directional boost converter, buck charger with battery state of health detection function designed for backup power systems like TBOX or eCall. The converter supports absolute maximum voltage up to 40V on the VOUT pin to withstand load-dump condition and supports direct connection with 12V car battery. The TPS61383-Q1 integrates I2C configurable buck/LDO charger supporting NiMH, Li-Ion, LiFePO4, super capacitor.

TPS61383-Q1 integrates boost function that operates over 0.5V to 12V BUB voltage and 5V – 12V output voltage. The device applies fix frequency peak current control scheme with optional spread spectrum to minimize EMI. The boost function supports 5A – 30A programmable average current limit.

The TPS61383-Q1 integrates battery health detection feature, which discharges the battery with a constant current and detects the voltage drop across the battery internal resistance.

The TPS61383-Q1 is available in a 3mm × 4mm QFN package with wettable flank. Care must be taken when designing the PCB with TPS61383-Q1. See also Layout Example.
