Datasheet
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.
2. Features
1 chip hall sensor/drivers
Wide operating voltage range: 4V~20V
Output sink current up to 0.35A
Low quiescent supply current under 5mA
