Input section
An Single ended Input TTL/CMOS compatible with wide voltage range and high noise
immunity (thanks to a built in hysteresis) is available.
Overtemperature protection (OVT)
An on-chip over temperature protection provides an excellent protection of the device in
extreme conditions. Whenever the temperature - measured on a central portion of the chip

Undervoltage protection (UV)
The supply voltage is expected to range from 8 to 35 V. In this range the device operates
correctly. To avoid any malfunctioning the supply voltage is continuously monitored to
provide an under voltage protection. As V

Normal operation is resumed as soon as Vs exceeds Vsth. The hysteretic behaviour
prevents intermittent operation at low supply voltage.
