General Description
The M5938A/B/C is a N-channel MOSFET power
switch designed for high-side load-switching applica-
tions, and the device has a typical R_DS(ON) of 5.5mΩ /
11mΩ / 22mΩ and the output current is limited to 10A /
6A / 4A.
In the M5938A/B/C, a discharge path is added for
quick output discharge when the switch is turned off.
The rise time of the device is internally controlled in
order to avoid in-rush current and can be adjusted
using a ceramic capacitor on the GATE pin.
The M5938A/B/C is available in TDFN3X3-8, MSOP-8
(FD) and SOT-23-6 package.
