5 / 16 page L6219R Block diagram & pins description 5/16 1 Block diagram & pins description Figure 1. Block diagram Figure 2. Pin connection (Top view) Table 1. Pin description Pin # Name Description 1;2 OUTPUT A See pins 5;21 3;23 SENSE RESISTOR Connection to Lower Emitters of Output Stage for Insertion of Current Sense Resistor 4;22 COMPARATOR INPUT Input connected to the comparators. The voltage across the sense resistor is feedback to this input throught the low pass filter RC CC. The higher power transistors are disabled when the sense voltage exceeds the reference voltage of the selected comparator. When this occurs the current decays for a time set by RT CT (toff = 1.1 RT CT). See fig. 4. 5;21 OUTPUT B Output Connection. The output stage is a "H" bridge formed by four transistors and four diodes suitable for switching applications. 6;19 GROUND See pins 7;18 |
