33886
5.0 A H-Bridge
The 33886 is a monolithic H-Bridge ideal for fractional horsepower
DC-motor and bi-directional thrust solenoid control. The IC incorporates
internal control logic, charge pump, gate drive, and low R
DS(ON)
MOSFET
output circuitry. The 33886 is able to control continuous inductive DC load
currents up to 5.0 A. Output loads can be pulse width modulated (PWM-ed)
at frequencies up to 10 kHz.
A Fault Status output reports undervoltage, short circuit, and
overtemperature conditions. Two independent inputs control the two half-
bridge totem-pole outputs. Two disable inputs force the H-Bridge outputs to
tri-state (exhibit high impedance).
The 33886 is parametrically specified over a temperature range of
-40°C

28 V. The IC can also be operated up to 40 V
with derating of the specifications. The IC is available in a surface mount
power package with exposed pad for heatsinking.

Exceeding the input voltage on IN1, IN2, D1, or D2 may cause a malfunction or permanent damage to the device.
Exceeding the pull-up resistor voltage on the open drain FS terminal may cause permanent damage to the device.
Continuous current capability so long as junction temperature is
≤

°
C.
ESD1 testing is performed in accordance with the Human Body Model (C
ZAP
= 100 pF, R
ZAP
= 1500
Ω).
ESD2 testing is performed in accordance with the Machine Model (C
ZAP
= 200 pF, R
ZAP
= 0
Ω).
All terminals are capable of Human Body Model ESD voltages of ±2000 V with two exceptions: (1) D2 to PGND is capable of ±1500 V and
(2) OUT1 to AGND is capable of ±1000 V.
The limiting factor is junction temperature, taking into account the power dissipation, thermal resistance, and heat sinking.
Terminal soldering temperature limit is for 10 seconds maximum duration. Not designed for immersion soldering. Exceeding these limits may
cause malfunction or permanent damage to the device.
Exposed heat sink pad plus the power and ground terminals comprise the main heat conduction paths. The actual R

JB
(junction-to-PC
board) values will vary depending on solder thickness and composition and copper trace.A
