EUP3546 - Dual Power-Distribution Switch

General Description

The EUP3546 incorporates dual 95mΩ P-channel MOSFET power switches for power-distribution systems that require multiple power switches in a single package.

Each switch is controlled by a logic enable input.

EUP3546 Dual Power-Distribution Switch with Fault-Blanking DESCRIPTION The EUP3546 incorporates dual 95mΩ P-channel MOSFET power switches for power-distribution systems that require multiple power switches in a single package. Each switch is controlled by a logic enable input. When either output load exceeds the current-limit threshold or a short is present, the device limits the outputs current to a safe level by switching into a constant-current limit mode with fold back, pulling the over-current (OCB(s)) logic output low. When continuous heavy overloads or short-circuits increase the power dissipation in the switches, causing the junction temperature to raise, a thermal protection circuit shutdown the switches to prevent damage.
