| Supply Voltage Range | 4.5 – 40 Vdc |
|---|---|
| Sense Trip Voltage | 2.45 – 2.75 Vdc |
| Output Current | 300 mA |
| Operating Ambient Temperature Range | 0 to +70 °C |
| Propagation Delay Time | 0.5 – 1.0 µs |
The trip voltage is adjustable between 2.45 V and 2.75 Vdc at 25°C.
Connect a capacitor from Pin 3 to VEE; the capacitor value determines the minimum duration of overvoltage before tripping.
The maximum output current is 300 mA.
The operating ambient temperature range is 0 to +70 °C.
