TPSI3052 Datasheet Isolated Switch Driver

Manufacturer: Texas Instruments

Overview: TPSI3052 SLVSGS3A – APRIL 2022 – REVISED APRIL 2023 TPSI3052 Isolated Switch Driver with Integrated 15-V Gate Supply.

General Description

The TPSI3052 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 15 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 TPSI3052 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.
  • 3-kVRMS basic isolation.
  • 15-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 functional.
