2 Phase DC Motor Drive IC
ES211
1.
Description
The ES211, a 1-chip composed of hall sensor and output coil drivers, applied to 2-phase DC motor.
The high sensitivity of Hall Effect sensor is suitable for motors from mini-type CPU coolers to blowers and DC fans.
The device also include an amplifier that amplifies the Hall voltage, and a Schmitt trigger to provide switching hysteresis for noise rejection, and complementary open-collector drivers for sinking large current loads.
An internal bandgap regulator is used to provide temperature compensated supply voltage for internal circuits and allows a wide operating supply voltage.
Typical operation current is 0.
3A and operating voltage range is wide.
FG single, an open collector, provides a square waveform output for the detection of the motor speed.
