... CIRCUIT DESCRIPTION 3.1 POWER STAGES and CHARGE PUMP The L6229 integrates a Three-Phase Bridge, which consists of 6 Power MOSFETs connected as shown on the Block Diagram. Each Power MOS has an R diode. Switching patterns are generated by the PWM Current Controller and the Hall Effect Sensor Decoding Logic (see relative paragraphs) ...

... OUTPUT 3.3 PWM CURRENT CONTROL The L6229 includes a constant off time PWM Current Controller. The current control circuit senses the bridge current by sensing the voltage drop across an external sense resistor connected between the source of the three lower power MOS transistors and ground, as shown in Figure 10. As the current in the motor increases the voltage across the sense resistor increases proportionally ...

... L6229 3.7 NON-DISSIPATIVE OVERCURRENT DETECTION and PROTECTION The L6229 integrates an Overcurrent Detection Circuit (OCD) for full protection. This circuit provides Output-to- Output and Output-to-Ground short circuit protection as well. With this internal over current detection, the exter- nal current sense resistor normally used and its associated power dissipation are eliminated. Figure 20 shows a simplified schematic for the overcurrent detection circuit ...
