3195 PROTECTED, HIGH-TEMP., ACTIVE PULL-DOWN HALL-EFFECT LATCH 3195 These Hall-effect latches are capable of sensing magnetic fields while using an unprotected power supply. The A3195– can provide position and speed information by providing a digital output for magnetic fields that exceed their predefined switch points. These devices operate down to zero speed and have switch points that are designed to be extremely stable over a wide operating temperature and voltage range. The latching characteristics make them ideal for use in pulse counting applications when used with a multi-pole ring magnet. A 25 mA high-side driver combined with an active pull-down is especially useful for driving capacitive loads.
