RT9741CGV High-Side Power Switch

Description

The RT9741 is a cost-effective, low-voltage, single NMOSFET high-side Power Switch IC for USB application. Low switch-on resistance (typ. 100mΩ) and low supply current (typ. 50μA) are realized in this IC.

The RT9741CGV integrates an over-current protection circuit, a short fold back circuit, a thermal shutdown circuit and an under-voltage lockout circuit for overall protection. Furthermore, the chip also integrates an embedded delay function to prevent miss-operation from happening due to inrush-current. The RT9741 is an ideal solution for USB power supply and can support flexible applications since it is available in the SOT-23-3 package.

2. EXTREMELY HIGH dv/dt CAPABILITY
3. 100% AVALANCHE TESTED
4. VERY LOW INTRINSIC CAPACITANCES
5. GATE CHARGE MINIMIZED

 

Absolute maximum ratings

1. Drain-source Voltage (VGS = 0) : VDS = 900 V
2. Drain-gate Voltage (RGS = 20 kW): VDGR = 900 V
3. Gate- source Voltage : VGS = ±30 V
4. Drain Current (continuos) at TC = 25°C : ID = 5 A
5. Total Dissipation at TC = 25°C : Ptot = 80 W

 

Applications

1. HIGH CURRENT, HIGH SPEED SWITCHING
2. SWITH MODE POWER SUPPLIES (SMPS)
3. DC-AC CONVERTERS FOR WELDING EQUIPMENT
