† Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. 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.

‡ Unless otherwise indicated, voltages are reference to ground and currents are positive into and negative out of the specified terminals.

w In normal operation, VCC is powered through a current limiting resistor. Absolute maximum of 12 V applies when VCC is driven from a low

impedance source such that ICC does not exceed 30 mA (which includes gate drive current requirement).

electrical characteristics, TA = −40_C to 125_C for Q temp and TA= −55_C to 125_C for M temp, VCC

= 10 V (see Note 1), RT = 100 kΩ from REF to RC, CT = 330 pF from RC to GND, 0.1 F capacitor from

VCC to GND, 0.1 F capacitor from VREF to GND and TA = TJ (unless otherwise stated)
