4 Input section
An Input and Asynchronous RESET, both TTL/CMOS compatible with wide voltage range
and high noise immunity (thanks to a built in hysteresis) are 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 Tmax =150 °C (typical value) the device is shut off, and the DIAG output goes LOW.
Normal operation is resumed as the chip temperature (normally after few seconds) falls
below Tmax-Thys = 130 °C (typical value). The hysteresis avoid thats an intermittent
behaviour take place. Under voltage protection (UV)
The supply voltage is expected to range from 8 to 35 V. In this range the device operates
correctly. Below 8V the overall system has to be considered not reliable. To avoid any
misfunctioning the supply voltage is continuously monitored to provide an under voltage
protection. As Vs falls below Vsth-Vshys (typically 7.5 V, see fig. 4) the output power MOS is
switched off and DIAG output goes LOW. Normal operation is resumed as soon as Vs
exceeds Vsth. The hysteretic behaviour prevents intermittent operation at low supply voltage.
