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 comp ensated 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
