Description

ET1511A/B is an infrared filter switch driver IC

which designed for filter control driving in IR cut

module in camera. ET1511A/B could functions as a

one-channel, low output headroom voltage,

bi-directional H-bridge driver by appropriate input

controls. Build-in protection diode circuit can

minimize the disturbance caused by the feedback

current when IR cut is shutdown or ESD transient

pulses appeared.

The output driver impedance of ET1511A/B is 2?

in typical. The current driven through the actuator is

determined by the impedance of the IR cut. In case

of 5V power supply, the 300mA driving current

through actuator is around 300mA with 0.48V output

voltage headroom.

There are 2 versions (Ver. A and Ver. B) of

ET1511, which offers to support single-wire input

control, dual-wire input control, and one-shot control.

In one-shot control mode, the on time could be

configured by external capacitor.
