If the input signal from the micro happens to remain high, the device protects itself against over-heating by forcing collector current to smooth decrease (low voltage clamp feature) and no undesidered spark occurs (see figure 4). BD VCC t e l o bs 1 s b O t c u d o r Pr PowerSO-10™ DESCRIPTION The VB326SP is a high voltage power integrated circuit made using the STMicroelectronics VIPower™ M1-3 technology, with vertical current flow power darlington and logic level compatible driving circuit. The enable pin allows to externally block the switch when the input is on. Built-in protection circuit for coil current limiting and collector voltage clamping allows the device to be used as smart, high voltage, high current interface BLOCK DIAGRAM u d o 10 HVC VIN DRIVER O QUASI PROP.
