Description
See pins 5;21
Connection to Lower Emitters of Output Stage for Insertion of Current Sense Resistor
4;22
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. 1.
Output Connection. The output stage is a "H" bridge formed by four transistors and
four diodes suitable for switching applications.
See pins 7;18
Ground Connection. With pins 6 and 19 also conducts heat from die to printed circuit
copper.
See INPUT 1 (pins 9;17)
These pins and pins 8;20 (INPUT 0) are logic inputs which select the outputs of the
comparators to set the current level. Current also depends on the sensing resistor and
reference voltage. See Funcional Description.
This TTL-compatible logic inputs sets the direction of current flow through the load. A
high level causes current to flow from OUTPUT A (source) to OUTPUT B (sink). A
schmitt trigger on this input provides good noise immunity and a delay circuit prevents
output stage short circuits during switching.
A voltage applied to this pin sets the reference voltage of the comparators, this
determining the output current (also thus depending on Rs and the two inputs INPUT
0 and INPUT 1).
A parallel RC network connected to this pin sets the OFF time of the higher power
transistors. The pulse generator is a monostable triggered by the output of the
comparators (toff = 1.1 RT CT).
