SiP32454, SiP32455
Vishay Siliconix
0.8 V to 2.5 V, 28 mΩ, Slew Rate Controlled Load Switch in WCSP4
DESCRIPTION
The SiP32454 and SiP32455 are slew rate controlled
integrated high side load switches that operate in the input
voltage range from 0.8 V to 2.5 V. The SiP32454 and
SiP32455 are of N-channel MOSFET switching elements
that provide 28 mΩ switch on resistance. They have a 1 ms
at 1.2 V and 1.5 ms at 2.5 V slow slew rate that limits the
in-rush current and minimizes the switching noise. These
devices’ low voltage logic control threshold can interface with
low voltage control I/O directly without extra level shift or
driver. A 2 MΩ pull-down resistor is integrated at logic control
EN pin. SiP32454 integrates a switch OFF output discharge
circuit.
Both SiP32454 and SiP32455 are available in compact wafer
level CSP package, WCSP4 0.8 mm x 0.8 mm with 0.4 mm
pitch.
