Datasheet Summary
2 Phase DC Motor Drive IC
1. Description
The ES211, a 1-chip posed 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 plementary open-collector drivers for sinking large current loads. An internal bandgap regulator is used to provide temperature pensated supply voltage for internal circuits and allows a wide operating supply voltage.
Typical operation current is 0.3A and operating...
