The W83L351 series are the power interface switch ICs for single slot ExpressCard and provide all power management functions required by ExpressCard. The W83L351 series distribute 3.3V, 3.3Vaux, and 1.5V to the ExpressCard socket. Each voltage line is protected with a built-in current limit circuit and a thermal shutdown circuit.
The W83352 series are high-side current-limited switches with enable and error flag functions, optimized for general purpose power distribution and Universal Serial Bus (USB) requiring circuit protection.
