ELECTRICAL CHARACTERISTICS (Values are noted under conditions of 7.0 V ≤ VCC ≤ 24 V, –40°C ≤ TA ≤ +125°C, unless otherwise
noted. Typical values reflect approximate mean at TA = 25°C at time of device characterization.)

NOTES: 1. The total supply current into Pin 2 and Pin 5 with RX = 100 k (from Pin 2 to supply) and 45 k pull–up resistor from Pin 6 to supply.
2. An internal zener clamp is provided to protect the device from overvoltage transients on the supply line.
3. The timer current constant is the proportionality constant of the voltage to current converter used to monitor the VDS voltage developed across the
FET (from Pin 1 to the supply).
4. The gate voltage will be clamped at approximately 7.0 V above the source voltage whenever the source voltage is less than approximately 1.0 V
above ground.
