Product details

Dual 500 mA high-side switch with Status Flag

Fault protection set — fixed current limit, overtemperature, UVLO

Built-in fault protection includes fixed current limiting, overtemperature shutdown, and undervoltage lockout (UVLO). These are self-contained — no external sense resistor or comparator needed. The fixed current limit is not adjustable, so the 500 mA per-channel rating is the hard ceiling; the load must stay within that budget including inrush. UVLO holds the switch off until the input supply is stable, which avoids glitches on power-up.

Frequently asked questions

Can TPS2082D handle 3.3 V logic input on the enable pin?

The On/Off interface is non-inverting and the input type is listed as Non-Inverting. The part operates from a load supply of 2.7 V to 5.5 V, and the logic input thresholds are compatible with both 3.3 V and 5 V logic levels — no separate Vcc supply is required.

What does the Status Flag feature do?

The Status Flag pin provides a fault indication output. It asserts when the device enters current limit, overtemperature shutdown, or undervoltage lockout. This allows a system controller to detect overcurrent or thermal fault conditions without external sense components.
