DESCRIPTION

The VN380 is a monolithic device made using STM VIPower Technology, intended for driving inductive loads. The inputs are CMOS compatible. The diagnostic output provides an indication of open load and demagnetization mode. Built-in thermal shut-down protects the chip from over-temperature. In case or over-current or over-temperature or over-voltage the product will automatically operate in recirculation mode. HEPTAWATT PowerSO-1O ORDER CODES: HEPTAWATT VN380 PowerSO-1O VN380SP

• CURRENT CUT OFF When the load current rise above the current cut off level, S1 is automatically switched off and the devices operates in recirculation mode (S2 active). S1is latched off until A goes low and high again. This default is not displayed by diagnostic flag. - OPEN LOAD If the load current is below the open load current level, the flag of the open load block is activated but this default is displayed by the diagnostic output on the falling edge of input B and the diagnostic output is latched at low level until input A goes low and high again. In case an open load is detected during an active phase of input B, but disappears before a falling edge of input B, this default is not dispayed by the diagnostic flag (see open load waveforms). - THERMAL SHUTDOWN The device is internally protected against over temperatures by the thermal circuit protection. When the device junction temperature exceeds the protection limit, S1 is automatically switched off. Therefore the device operates in recirculation mode (S2 active). S1 remain latched off until Vpwr1 goes low and high again. This default is not dispayed by the diagnostic flag. OVERVOLTAGE During the ON state of S1 switch, if V pwr1 or Vpwr2 is rising above the threshold detection S1 is automatically switched off, therefore the device operates in recirculation mode.
