MC33HB2000
Rev. 6.0 — 9 August 2018
10 A H-bridge, SPI programmable brushed DC motor driver
Data sheet: advance information

General description
The MC33HB2000 is a SMARTMOS monolithic H-Bridge Power IC, enhanced with SPI
configurability and diagnostic capabilities. It is designed primarily for DC motor or servo
motor control applications within the specified current and voltage limits.
The MC33HB2000 is able to control inductive loads with peak currents greater than 10 A.
The nominal continuous average load current is 3.0 A. A current mirror output provides
an analog feedback signal proportional to the load current.
This part is designed to specifically address the ISO 26262 safety requirements. It meets
the stringent requirements of automotive applications and is fully AEC-Q100 grade 1
qualified.

Features and benefits
•
Advanced diagnostic reporting via a serial peripheral interface (SPI): charge pump
undervoltage, overvoltage, and undervoltage on VPWR, short to ground and short
to VPWR for each output, open load, temperature warning and overtemperature
shutdown
•
Thermal management: Excellent thermal resistance of <1.0 °C/W between junction and
case (exposed pad)
•
Eight selectable slew rates via the SPI: 0.25 V/μs to more than 16 V/μs for EMI and
thermal performance optimization

•
Four selectable current limits via the SPI: 5.4/7.0/8.8/10.7 A covering a wide range of
applications
•
Three package sizes available in SOIC, PQFN and HVQFN to meet footprint and
application requirement
•
Can be operated without SPI with default slew rate of 2.0 V/μs and a 7.0 A current limit
threshold
•
Highly accurate real-time current feedback through a current mirror output signal with
less than 5.0 % error
•
Drives inductive loads in a full H-bridge or Half-bridge configuration
•
Overvoltage protection places the load in high-side recirculation (braking) mode with
notification in H-bridge mode
•
Wide operating range: 5.0 V to 28 V operation
•
Low R
DS(on)
integrated MOSFETs: Maximum of 235 mΩ (T
J
= 150 °C) for each
MOSFET
•
Internal protection for overtemperature, undervoltage, and short-circuit by signaling the
error condition and disabling the outputs
•
I/O pins can withstand up to 36 V
•
AEC-Q100 grade 1 qualified

VPWR
When ENBL is logic HIGH, the H-bridge is
operational. When ENBL is logic LOW, the H-
bridge outputs are tri-stated and placed in Sleep
mode.
When DIS is logic HIGH, both OUT1 and OUT2
are tri-stated
Logic input control of OUT2
Logic input control of OUT1
The load current feedback output provides ground
referenced 0.25 % of the high-side output current.
Open drain active LOW status flag output
These pins must be connected together physically
as close as possible and directly soldered down
to a wide, thick, low resistance supply plane on
the PCB.
