These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating conditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. (2) Package thermal impedance is calculated in accordance with JESD 51-7. over operating free-air temperature range (unless otherwise noted) MIN MAX UNIT VCC Supply voltage 4 28 V VH Hall amplifier input voltage 1 VCC – 0.5 V TA Operating free-air temperature –40 100 °C VCC = 12 V, TA = 25°C (unless otherwise noted) PARAMETER TEST CONDITIONS MIN TYP MAX UNIT VHYS Hall amplifier input voltage hysteresis ±3 ±15 mV VAL Lock alarm signal low-level output voltage AL IAL = 5 mA 0.5 V IAL Lock alarm signal low-level output current AL VAL = 2 V 8 mA ILDC Lock detection capacitor charge current LD VLD = 1.5 V 2 3.45 5.25 µA ILDD Lock detection capacitor discharge current LD VLD = 1.5 V 0.35 0.8 1.45 µA Lock detection capacitor charge/discharge rCD LD rCD = ILDC/ILDD 3 4.5 8 current ratio VLDCL Lock detection capacitor clamp voltage LD 2.2 2.6 3 V VLDCP Lock detection capacitor comparator voltage LD 0.4 0.6 0.8 V V7H High-level output voltage A1 IOH = –10 mA 10 10.5 V V8H High-level output voltage A2 IOH = –10 mA 10 10.5 V ICC Supply current Output off 3.2 5 mA Copyright © 2008, Texas Instruments Incorporated Submit Documentation Feedback 3 |
