Description
Single Output Hall Effect Latch IC
The G177 is an integrated Hall effect latched sensor with output pull-high resistor driver designed for electronic mutation of brushless DC motor applications and contactless switches. The device includes an on-chip Hall voltage generator for magnetic sensing, a parator 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 pensated 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). G177 is rated for operation over temperature range from -20 to 100 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 pensated 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.
