TPSI31P1-Q1 Active Pre-Charge Controller

Texas Instruments TPSI31P1-Q1 Active Pre-Charge Controller 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, a power inductor, and a 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 charge the large capacitance of the downstream system linearly. 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, including SiC FET and IGBT, can be used.
