1 / 10 page 3195 PROTECTED, HIGH-TEMP., ACTIVE PULL-DOWN HALL-EFFECT LATCH 3195 PROTECTED, HIGH-TEMPERATURE, HALL-EFFECT LATCH WITH ACTIVE PULL-DOWN Always order by complete part number, e.g., A3195LU . 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 mag- netic 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 espe- cially useful for driving capacitive loads. Output short-circuit protection allows for an increased wiring harness fault tolerance. The tempera- ture compensated switch points, the wide operating voltage range, and the integrated protection make these devices ideal for use in automo- tive applications such as transmission speed sensors and integrated wheel bearing speed sensors. Each monolithic device contains an integrated Hall-effect trans- ducer, a temperature-compensated comparator, a voltage regulator, and a buffered high-side driver with an active pull-down. Supply protection is made possible by the integration of overvoltage shutdown circuitry that monitors supply fault conditions. Output protection circuitry includes source and sink current current limiting for short circuits to supply or ground. The A3195E– is rated for operation over a temperature range of -40 °C to +85°C; the A3195L– is rated for operation over an extended temperature range of -40 °C to +150°C. They are supplied in a three- lead SIP (suffix –U) or a surface-mount SOT-89 (suffix –LT).
