TPSI3050-Q1 Datasheet Automotive Reinforced Isolated Switch Driver

Manufacturer: Texas Instruments

Overview: TPSI3050-Q1 SLVSFJ7C – NOVEMBER 2021 – REVISED APRIL 2023 TPSI3050-Q1 Automotive Reinforced Isolated Switch Driver with Integrated 10-V Gate Supply.

General Description

The TPSI3050-Q1 is a fully integrated, isolated switch driver, which when combined with an external power switch, forms a complete isolated Solid State Relay (SSR).

With a nominal gate drive voltage of 10 V with 1.5/3.0-A peak source and sink current, a large variety of external power switches can be chosen to meet a wide range of applications.

The TPSI3050-Q1 generates its own secondary bias supply from the power received from its primary side, so no isolated secondary supply bias is required.

Key Features

  • No isolated secondary supply required.
  • Drives external power transistors or SCRs.
  • 5-kVRMS reinforced isolation.
  • 10-V gate drive with 1.5/3-A peak source and sink current.
  • Up to 50-mW supply for external auxiliary circuitry.
  • Supports AC or DC switching.
  • Supports two-wire or three-wire modes.
  • Seven levels of power transfer, resistor selectable.
  • Functional Safety-Capable.
  • Documentation available to aid functi.
