The TPS16530 is a 58-V industrial eFuse. The device provides robust protection for all systems and applications powered from 4.5 V to 58 V. For hot-pluggable boards, the device provides hot-swap power management with in-rush current control and programmable output voltage slew rate features using the dVdT pin. Load, source and device protections are provided with many programmable features including overcurrent and undervoltage. The precision overcurrent limit (±7% at 6 A) helps to minimize over design of the input power supply, while the fast response short circuit protection 1 µs (typical) immediately isolates the faulty load from the input supply when a short circuit is detected.

The device provides precise monitoring of voltage bus for brown-out and overvoltage conditions and asserts fault signal for the downstream system. The device's overall threshold accuracy of 2% ensures tight supervision of bus, eliminating the need for a separate supply voltage supervisor chip.

Additional features of the TPS16530 include:

• ±6% current monitor output (IMON) for health monitoring of the system
• A choice of latch off or automatic restart mode response during current limit and thermal fault using MODE pin
• PGOOD indicator output
• Over temperature protection to safely shutdown in the event of an overcurrent event
• De-glitched fault reporting for faults
• Enable and Disable control from an MCU using EN pin
• Low power shutdown using SHDN pin
