H-Bridge Driver
The 33186 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 33186 is able to control
continuous inductive DC load currents up to 5.0 A. Output loads can
be pulse width modulated (PWMed) at frequencies up to 10 kHz. This
device is powered by SMARTMOS technology.
The 33186 is parametrically specified over a temperature range of

When connected to VCC, the disable Pin DI1 and DI2 are inactive. A stored failure will be reset by

Description
The Pins 4 and 5 are internally connected. These Pins supply the left high side and the analog/logic
part of the device.
The Pin 16 supplies the right high side and the charge pump.
The Pins 4, 5 and 16 should be connected together on the printed circuit board with connections as
short as possible.

from switching transients.
Supervision and protection functions
a) Supply voltage supervision
The supply voltage is supervised. If it is below its specific threshold, the power stages are switched
in tristate and the status flag is switched low.
If the supply voltage is over the specific threshold again, the power stage switches independently
into normal operation, according to the input Pins and the status flag is reset.
b) Thermal supervision
In case of overtemperature, the power stages are switched in tristate independent of the inputs
signals and the status flag is switched low.
If the level changes from high to low on DI1 (IN1) or low to high on DI2 (IN2), the output stage
switches on again if the temperature is below the specified limit.The status-flag is reset to high level
(Pin names in brackets refer to coding Pin = VCC).
c)
Supervision of overcurrent on high sides and low sides
In case of overcurrent detection, the power stages are switched in tristate independent of the inputs
signals and the status flag is set.
If the level changes from high to low on DI1 (IN1) or low to high on DI2 (IN2) the output stage
switches on again and the status flag is reset to high level (Pin names in brackets refer to coding
Pin = VCC).
The output stage switches into the mode defined by the inputs Pins provided, and/if the temperature
is below the specified limits.
d) Current limiting on low sides
The maximum current which can flow under normal operating conditions is limited to Imax = 6.5 A
20%.
When the maximum current value is reached, the output stages are switched tristate for a
fixed time. According to the time constant the current decreases until the next switch on occurs. See

Charge Pump output Pin
A filtering capacitor (up to 33 nF) can be connected between Pin 17 and GND. Device can operate
without external capacitor, although Pin 17 decoupling capacitor help in noise reduction and allows
the device to perform a maximum speed, timing and PWM frequency.

Notes
1. 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.
2. Freescale’s Package Reflow capability meets Pb-free requirements for JEDEC standard J-STD-020C. For Peak Package Reflow
