Application
The HIP4020 is designed to detect load current feedback
from sampling resistors of low value in the source
connections of the output drivers to V DD , V SSA and V SSB
(See Figure 1). When the sink or source current at OUTA or
OUTB exceeds the preset OC (Overcurrent) limiting value of
550mA typical, the current is held at the limiting value. If the
OT (Over-Temperature) Shutdown Protection limit is
exceeded, temperature sensing BiMOS circuits limit the
junction temperature to 150°C typical.

SWITCHING WAVEFORMS
FIGURE 2.
The circuit of Figure 1 shows the Full H-Switch in a small motor-
drive application. The left (A) and right (B) H-Switch’s are
controlled from the A and B inputs via the A and B CONTROL
LOGIC to the MOS output transistors Q1, Q2, Q3 and Q4. The
circuit is intended to safely start, stop, and control rotational
direction for a motor requiring no more than 0.5A of supply
current. The stop function includes a Dynamic Braking feature.
With the ENABLE Inputs Low, the MOS transistors Q1 and Q3
are OFF; which cuts-off supply current to OUTA and OUTB.
With the BRAKE terminal Low and ENABLE Inputs High, either
Q1 and Q4 or Q3 and Q2 will be driven into conduction by the
FN3976.3
