Anachip ATS278

ATS278 is an integrated Hall sensor with two output drivers and rotor speed output, typically designed for electronic commutation of two-phase brush-less DC fan applications. The amplifier will amplify the Hall voltage. The Schmitt trigger determines switching hysteresis and then control internal driver’s on/off to sink load current.

FEATURES

- On-chip Hall plate - Operating voltage: 3.5V~20V - Internal bandgap regulator allows temperature compensated operations and a wide operating voltage range - High output sinking capability up to 400mA for driving large load - Built-in protection diode only for chip reverse power connecting - Frequency Generation (FG) output - Package: SIP-5L „

GENERAL DESCRIPTION

On-chip Hall sensor will generate Hall voltage due to magnetics sensing. The amplifier will amplify the Hall voltage. Meanwhile, An internal bandgap regulator is used to provide stable bais due to temperature-compensation. FG pin will provide switching frequency of driver. Major feature is to minimize the external components by building-in FG output transistor. If a magnetic flux density larger than threshold Bop, DO is turned on (low) and DOB is turned off (high). The output state is held until a magnetic flux density reversal falls below Brp causing DO to be turned off and DOB turned on. „
