D6211
D6211 is an IR filter switch driver IC designed for switching IR filter in IR-Cut Removable (ICR) of IP CAM. With appropriate input controls, D6211 functions as a one-channel, low saturation, bi-directional H-bridge driver. Built-in protection diode circuit can minimize the disturbance caused by the feedback current when the ICR is shut down, or when ESD impulse occurs.
The typical impedance of the current switches in D6211 shown in Fig. 1 is less than 3 ohms. The current driven through the actuator is then determined by the impedance of the ICR. For example, with 5.0V power supply, the current through the actuator is around 300mA with 0.73V output voltage drop.
Two types of D6211 (Ver. A & Ver. B) are offered to support single-wire control, dual-wire control and single-wire one-shot control modes as shown in Fig.Typical Application Circuit.
D6211 is offered in SOT-23-6L package.
