Texas Instruments TPS16530 58V 4.5A Electronic Fuse

Texas Instruments TPS16530 58V 4.5A eFuse is a simple to use positive eFuse with an integrated 31mΩ FET. The device provides protection for the load, the power supply, and the e-fuse itself, with various adjustable features such as accurate overcurrent protection, fast short-circuit protection, output slew rate control, and undervoltage lockout. PGOOD can be used to enable and disable downstream DC/DC converter control.

The enable pin provides external control for enabling and disabling the internal FETs. A shutdown pin can be used to place the device in a low-power shutdown mode. For system status monitoring and downstream load control, the device provides fault and precision current monitoring outputs. The MODE pin can be used to flexibly configure the device between two current-limit fault responses (latchoff and auto-retry).

Texas Instruments TPS16530 is available in 20-pin HTSSOP and 24-pin VQFN packages and is specified over the –40°C to +125°C operating temperature range.
