The TPSI31P1-Q1 is designed to be used in automotive pre-charge systems as an alternative to traditional passive pre-charge architectures that typically include costly electromechanical relays (EMR), along with bulky, high power resistors. The TPSI31P1-Q1, combined with external power switches, power inductor and diode, forms an active pre-charge solution. The inductor current is continuously monitored and controlled in a hysteretic mode of operation by the TPSI31P1-Q1 to linearly charge the large capacitance of the downstream system. The TPSI31P1-Q1 is an isolated switch driver that generates its own secondary bias supply from power received on its primary side, therefore no isolated secondary supply is required. With a gate drive voltage of 17V with 1.5A and 2.5A peak source and sink current, a large availability of power switches can be used including SiC FET and IGBT.

The TPSI31P1-Q1 integrates a communication back-channel that transfers status information from the secondary side to the primary side via open-drain output, PGOOD (Power Good) and indicates when the secondary power is valid.

The TPSI31P1-Q1 reinforced isolation is extremely robust with much higher reliability, lower power consumption, and increased temperature ranges than those found in optocouplers. Replacing the EMR and power resistor with a solid state solution can lead to reduced cost and form factor, while providing higher reliability.
