Description

The VB125ASPTR-E is a high voltage power integrated circuit made using the

STMicroelectronics™ VIPower™ M1-2 technology, with vertical current flow power darlington and logic level compatible driving circuit.

The VB125ASPTR-E can be directly biased by using the 12 V battery voltage, thus avoiding to use a low voltage regulator. It has built-in protection circuit for coil current limiting and collector voltage clamping. It is suitable as smart, high voltage, high current interface in advanced electronic ignition system.

1.

In the high voltage clamping structure of this device a temperature compensation has been implemented.

The circuit schematic is shown in

2.

The saturation voltage of the Power stage includes the drop on the sensing resistor.

3.

Considering the different ways of operation of the device (with or without spark, etc...) there are some short periods of time in which the output terminal (HV

C

) is pulled below ground by a negative current due to leakage inductances and stray capacitances of the ignition coil. With VIPower devices, if no corrective action is taken, these negative currents can cause parasitic glitches on the diagnostic output. To kill this potential problem, a circuit that avoids the possibility for the HV

C

to be pulled underground, by sending the required negative current from the battery is implemented in the VB125ASPTR-E. For this reason there are some short periods in which a current exceeding 220 mA flows in the V

CC

pin.

4.

A zener protection of 16 V (typical) is placed on the supply pin (V

CC

) of the chip to protect the internal circuitry. For this reason, when the battery voltage exceeds that value, the current flowing into V

CC be greater than the maximum current specified at V it will be limited by an internal resistor.

CC

= 14 V (both in power on and power off conditions):

5.

The primary coil current value I cl

must be measured 1 ms after desaturation of the power stage.

6.

These limits apply with regard to the minimum battery voltage and resistive drop on the coil and cables that permit to reach the limitation or diagnostic level.

No internal pull-down.

, the diagnostic output voltage rises to the high level and so it remains until the

T jmin

= 150 °C means that the behavior of the device will not be affected for junction temperature lower than 150 °C. For higher temperature, the thermal protection circuit begins its action reducing the I according with the power dissipation. Chip temperature is a function of the R th the device will be operating (See

Figure 6 ).
