Technical Data
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
RDS(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 (PWM-ed) at frequencies up to 10 kHz.
The 33186 is parametrically specified over a temperature range of
-40°C TA 125°C, 5.0 V V+ 28 V. The IC can also be operated
up to 40 V with de-rating of the specifications. The IC is available in a
surface mount power package with exposed pad for heat sinking.
Features

Protection against Transients up to 40 V at VBAT Typical
• RDSon = 150 mfor each output Transistor at 25°C
• Continuous DC Load Current 5 A (TC < 100°C)
• Output Current Limitation at typ 6,5 A +/- 20%
• Short-Circuit Shutdown for Output Currents over 8 A
• Logic Inputs TTL/CMOS Compatible
• Operating Frequency up to 20 kHz
• Undervoltage Disable Function
• Diagnostic Output, 2 Disable Input
• Coding Input for Alternative Functions
• Stable Operation with an External Capacitance of Maximum 47 µF
at VBAT
• Pb-Free Packaging Designated by Suffix Code VW

COD
Open drain output, active low. Is set according to the truth table. When a fault appears, SF changes
typically in less than 100 ms.
Voltage controlled inputs with hysteresis
When not connected or connected to GND, a stored failure will be reset by change of the voltage-
level on DI1 or DI2.
When connected to VCC, the disable Pin DI1 and DI2 are inactive. A stored failure will be reset by
change of the voltage-level on IN1 or IN2.
