EUP3542

EUP3542 Dual Power-Distribution Switch with Fault-Blanking DESCRIPTION The EUP3542 incorporates dual 100mΩ 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. Internal Under Voltage Lock-Out (UVLO) circuitry ensures that the switches remain off until valid input voltage is present. Each power switch is designed to set current limit at 1A_typical for EUP3542 and 2.5A_typical for EUP3542-15 respectively. OCB(s)...
