The purpose of this circuit is to shift the current level at which the first diagnostic is activated down of about 1A. The input VIN of the VB029, VB029SP, VB029(011Y) VB029(012Y) are fed from a low power signal generated by an external controller that determines both dwell time and ignition point. During VIN high (≥4V) the VB029, VB029SP, VB029(011Y) VB029(012Y) increase current in the coil to the desired, internally set current level. This information can be managed by the micro that can take the corrective action in order to reduce the power dissipation. This block is not an effective protection but just an overtemperature detection. The shift down of the first flag level cannot be present for temperatures lower than 125°C. When the collector current exceeds 4.5A, the diagnostic signal is turned high and it remains so, until the load current reaches 5.8A (second threshold). At that value, the diagnostic signal is turned low, and the µC forces the VIN to the low state. During the coil current switch-off, the primary voltage HVC is clamped by a series of Zener diodes at an internally set value Vcl, typically 360V. As an example of its behavior you can suppose a very simple motor management system in which the micro does just a simple arithmetic calculation to decide when to switch-off the device after the first flag threshold. The collector current sensed through the Rsense, is limited thanks to the “Current limiter” block that, as soon as the Icl level is reached, forces the darlington (using the “Driver” block) to limit the current provided. Iswitch-off info after kx ms. The transition from saturation to desaturation, coil current limiting phase, must have the ability to accommodate an overvoltage. A maximum overshoot of 20V is allowed. There can be some short period of time in which the output pin (HVC) is pulled below ground by a negative current due to leakage inductances and stray capacitances of the ignition coil. This can cause parasitic glitches on the diagnostic output. VB029, VB029SP, VB029(011Y) VB029(012Y) have a built-in protection circuit that allows to lock the p-buried layer potential of the linear stage to the collector power, when the last one is pulled underground. FIGURE 1: Application circuit 4/10 1 EXAMPLE: IC(DIAG1) info after x ms (IC(DIAG1)=2.5A) As soon as the temperature rises over the overtemp threshold, the first diagnostic is shifted down to about 1.5A and, in this example, the switch-off current will be kx*1.5 / 2.5.
