TPS1653 58 V 4.5 A eFuse with Pulse Current Support

Texas Instruments' eFuse provides robust protection for systems and applications powered from 4.5 V to 58 V

Image of Texas Instruments' TPS1653 eFuseTexas Instruments' TPS16530 is an easy-to-use, positive 58 V, 4.5 A eFuse with a 31 mΩ integrated FET. Protection is provided for the load, source, and the eFuse itself with adjustable features including accurate overcurrent protection, fast short-circuit protection, output slew rate control, and undervoltage lockout. Power Good (PGOOD) can enable and disable control of the downstream DC/DC converters.

The enable pin provides external control for enabling and disabling the internal FET. The shutdown pin can put the device in low power shutdown mode. For system status monitoring and downstream load control, the device provides fault and precise current monitor output. The MODE pin allows flexibility to configure the device between the two current-limiting fault responses (latch-off and auto-retry). The device is available in 20-pin HTSSOP and 24-pin VQFN packages and is specified over a temperature range of -40°C to +125°C.

Features
  • Operating voltage: 4.5 V to 58 V, 67 V (absolute max.)
  • Integrated 58 V, 31 mΩ RON hot-swap FET
  • Adjustable current limit: 0.6 A to 4.5 A (±7%)
  • IPC9592B clearance for 56 V operation (20-pin HTSSOP)
  • 2x pulse current support for load transients

  • Adjustable UVLO cut-off with ±2% accuracy
  • PGOOD
  • Adjustable output slew rate control for inrush current limiting
    • Charges large and unknown capacitive loads through thermal regulation during device power-up
  • Selectable overcurrent fault response options between auto-retry and latch-off (MODE)
  • Analog current monitor (IMON) output (± 6%)
  • Packages: easy-to-use 20-pin HTSSOP and 24-pin VQFN
Applications
  • Power amplifier protection in telecom radios
  • Medical equipment
  • Fire alarm control panels
  • Industrial printers
