Output Connection (with pin 15). The output stage is a "H" bridge formed by four
transistors and four diodes suitable for switching applications.
A parallel RC network connected to this pin sets the OFF time of the lower power
transistors. The pulse generator is a monostable triggered by the rising edge of
the output of the comparators (t

Ground Connection. With pins 5, 12 and 13 also conducts heat from die to
printed circuit copper.
See pin 4.
Supply Voltage Input for Logic Circuitry
This pin and pin 9 (INPUT 0) are logic inputs which select the outputs of the
three comparators to set the current level. Current also depends on the sensing
resistor and reference voltage. See truth table.
This TTL-compatible logic input 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.
See INPUT 1 (pin 7) .
Input connected to the three comparators. The voltage across the sense resistor
is feedback to this input through the low pass filter R
transistor 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
R
A voltage applied to this pin sets the reference voltage of the three comparators,
this determining the output current (also thus depending on R
INPUT 0 and INPUT 1).
