HI-SINCERITY MICROELECTRONICS GROUP. Spec. No. : IC200914 Issued Date : 2009.08.12 Revised Date :2010,01,18 Page No. : 1/6 H177 Single Output Hall Effect Latch IC General Description H177 is an integrated Hall effect latched sensor with output pull-high resistor driver designed for electronic commutation of brushless DC motor applications and contactless SIP-3L Package switches. The device includes an on-chip Hall voltage generator for magnetic sensing, a comparator that amplifies the Hall voltage, and a Schmitt trigger to provide switching hysteresis for noise rejection, and output driver with pull-high resistor. An internal bandgap regulator is used to provide temperature compensated supply voltage for internal circuits and allows a wide operating supply range.If a magnetic flux density larger than threshold Bop, DO is turned on (Low). The output state is held until a magnetic flux density reversal falls below Brp causing DO to be turned off (High). H177 is rated for operation over temperature range from -20℃ to 85℃ and voltage range from 3.5V to 28V. The devices are available in low cost die forms or rugged 3 pin SIP packages. Features • Wide range of supply voltage: 3.5V to 28V. • Internal bandgap regulator allows temperature compensated operations and a wide operating voltage range. • High sensitivity with a small magnet. • TTL and MOS ICs directly drivable by output. • Build in protection diode for chip reverse power connecting. • Package: SIP-3L. Applications • Brushless DC Motor • Brushless DC Fan • Position Sensors • Rotation Sensors • Revolution Counting • Speed Measurement • Keyboard Switches • Micro-switches H177 HSMC Product Specification HI-SINCERITY Spec.
