RT9736A
Dual Channel, Low Resistance Load Switch
General Description
The RT9736A is a small, low RON, dual channel load switch
with EN controlled pin. The product contains two N-
MOSFETs that can operate between an input voltage range
of 0.8V to 5.5V. Also, it supports a maximum current of
6A each channel. Each switch is independently controlled
by EN pins (EN1 and EN2), which can directly interface
with low-voltage control signals.
The RT9736A is available in the WDFN-14TL 3x2 package
with exposed pad for high power and heat dissipation.
