Vishay Siliconix SiP32458/59 Slew Rate Controlled Load Switches

Vishay Siliconix SiP32458/59 Slew Rate
Controlled Load Switches

Vishay Siliconix's SiP32458/59 Slew Rate Controlled Load Switches are slew rate controlled integrated high side load switches that operate in the input voltage range from 1.5V to 5.5V. The SiP32458/59 are made of a P-channel MOSFET switching element with integrated gate pump that provides 20mΩ switch on resistance over a wide input voltage range. These devices have low voltage logic control threshold that can interface with low voltage control I/O directly without extra level shift or driver. A 2.8 MΩ pull-down resistor is integrated at logic control EN pin. The slow slew rate of the SiP32458/59 is in the range of 3ms limits the in-rush current and minimizes the switching noise. The SiP32458 features a reverse current blocking capability while the SiP32459 features an integrated output discharge switch.
