... FULLY PROTECTED H-BRIDGE FOR D.C. MOTOR The IR3220S is a fully protected dual high side switch I.C that integrates an H–bridge motor controller with two very efficient high side MOSFETs in a single 20-pin package. The IR3220S combines with the two low side IRF7484Q MOSFETs as few as ...

... IR3220S Functional Block Diagram Soft Start duty cycle VCC IN 1 Over current Shoot-through protection Low Side G 1 Driver 50 Thanks to the self-adaptive dead-time circuitry, the low side MOSFET of each leg is driven in the opposite phase of the high side one without any conflict. Thus, the single IN1 signal turns on the leg M1 (and IN2, the output M2) ...

... Cres ( uF soft-start (A) x 25). The window-lifter is a good example where the IR 3220S’s PWM ability greatly en- hances the application. The current is monitored thanks to a shunt and sent back to the micro-controller which takes over the torque control loop (anti-pinch function). IR3220S +Bat Over-voltage protection S ...

... IR3220S In addition, the soft-start sequence pro- vides a smooth motion of the window. Torque or speed controls are also achievable without any micro-control- ler. With a few additional components, the IR 3220S can be the ‘’power stage‘’ overall analog control loop. The SS pin is then used as the PWM duty ...
