UNISONIC TECHNOLOGIES CO., LTD IR8511 Preliminary IR FILTER SWITCH DRIVER CMOS IC  DESCRIPTION UTC IR8511 is an IR filter switch driver IC designed for switching IR filter in IR-Cut (ICR). With appropriate input controls, UTC IR8511 is made up of a one-channel, low saturation, bi-directional H-bridge driver. The protection diode circuit built in UTC IR8511 can minimize the disturbance caused by the feedback current when ESD impulse occurs, or when the ICR is shut down. The typical impedance of the current switches in UTC IR8511 is less than 3Ohm. 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.
