CAUTION: Stresses above those listed in “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress only rating and operation of the

NOTES:
1. V
SS
is the required common ground reference for the logic input switching. The load currents may be switched positive and negative in reference
to the V
SS
common ground by using a split supply for V
DD
(positive) to V
SSA
and V
SSB
(negative). For an uneven split in the supply voltage,
the Maximum Negative Output Supply Voltage for V
SSA
and V
SSB
is limited by the Maximum V

to V
SSA
or V
SSB
ratings. Since the V
DD
pins
are internally tied together, the voltage on each V
DD
pins must be equal and common.

DESCRIPTION
Positive Power Supply pins; internally common and externally connect to the same Positive Supply (V+).
Negative Power Supply pin; Negative or Ground return for Switch Driver A; externally connect to the Supply
(V-).
Negative Power Supply pin; Negative or Ground return for Switch Driver B; externally connect to the Supply
(V-).
Common Ground pin for the Input Logic Control circuits. May be used as a common ground with VSSA and
V
SSB.
Input pins used to control the direction of output load current to/from OUTA and OUTB, respectively. When
connected, A1 and B1 can be controlled from the same logic signal to change the directional rotation of a
motor.
Input pins used to force a low state on OUTA and OUTB, respectively. When connected, A2 and B2 can be
controlled from the same logic signal to activate Dynamic Braking of a motor.
Input pins used to Enable Switch Driver A and Switch Driver B, respectively. When Low, the respective
output is in a high impedance (Z) off-state. Since each Switch Driver is independently controlled, OUTA and
OUTB may be a separately PWM controlled as Half H-Switch Drivers.
Respectively, Switch Driver A and Switch Driver B Output pins.
Current Limiting Fault Output Flag pin; when in a high logic state, signifies that Switch Driver A or B or both
are in a Current Limiting Fault Mode.

SWITCHING WAVEFORMS
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.
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
