20 m, Slew Rate Controlled Load Switch in WCSP6
DESCRIPTION
SiP32458 and SiP32459 are slew rate controlled integrated
high side load switches that operate in the input voltage
range from 1.5 V to 5.5 V.
SiP32458 and SiP32459 are of P-channel MOSFET
switching element with integrated gate pump that provides
20 m 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 M pull-down resistor is
integrated at logic control EN pin.
The slow slew rate of SiP32458 and SiP32459 in the range
of 3 ms limits the in-rush current and minimized the switching
noise.
The SiP32458 features a reverse current blocking capability
while the SiP32459 features an integrated output discharge
switch.
Both SIP32458 and SiP32459 are available in compact wafer
level WCSP package, WCSP6 1 mm x 1.5 mm with 0.5 mm
pitch.
