Innosen Technology ES211
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.| Part No. | ES211 |
