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 pin may cause permanent damage to the device.

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 pins are capable of Human Body Model ESD voltages of ±2000 V with two exceptions pertaining only to the DH suffix package: (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 heatsinking.
Pin 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.
Freescale’s Package Reflow capability meets Pb-free requirements for JEDEC standard J-STD-020C. For Peak Package Reflow
Temperature and Moisture Sensitivity Levels (MSL),
Go to www.freescale.com, search by part number [e.g. remove prefixes/suffixes and enter the core ID to view all orderable parts. (i.e.
MC33xxxD enter 33xxx), and review parametrics.
Exposed heatsink pad plus the power and ground pins comprise the main heat conduction paths. The actual R
θ
JB
(junction-to-PC board)
values will vary depending on solder thickness and composition and copper trace.
