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.
Over temperature 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
exceeds T
LOW. Normal operation is resumed as the chip temperature (normally after few seconds)
falls below T

Under voltage protection (UV)
The supply voltage is expected to range from 8 to 35V. In this range the device operates
correctly. To avoid any misfunctioning the supply voltage is continuously monitored to
provide an under voltage protection. As V
the output power MOS is switched off and DIAG1 and DIAG2 (see Diagnostic truth table).
Normal operation is resumed as soon as Vs exceeds Vsth. The hysteretic behaviour
prevents intermittent operation at low supply voltage.
