RT9724
100mΩ, 2A Slew Rate Controlled Load Switch
General Description
The RT9724 is a cost-effective, low-voltage, single
N-MOSFET high-side Power Switch IC. Low switch-on
resistance (typ. 100mΩ) and low supply current (typ. 50uA)
are realized in this IC. The RT9724 integrates an over-
current protection circuit, a short fold back circuit, a
thermal shutdown circuit and an under-voltage lockout
circuit for overall protection. Besides, a slew rate
controlled function is embedded for turn-on rising time
control. The RT9724 is available in SOT-23-5 and WDFN-
8L 2x2 package.
