G177
G177 - Brand New ASTEC IC Chips
Credit Card - One-month free return and one year warranty.
- Full or Partial Refund, if the item is not as described
- Full Refund if you don't receive your order
Description
The G177 is an integrated Hall effect latched sensor with output pull-high
resistor driver designed for electronic commutation of brushless DC motor
applications and contactless 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).
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 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.
Application
1) Brushless DC Motor
2) Brushless DC Fan
3) Position Sensors
4) Rotation Sensors
5) Revolution Counting
6) Speed Measurement
7) Keyboard Switches
8) Microswitches
