Description
Features
MC33HB2001
The 33HB2001 is a monolithic H-Bridge
Power IC, enhanced with SPI configurability
and diagnostic capabilities.
•
Advanced diagnostic reporting via a serial peripheral
interface (SPI): charge pump 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
•
Can be operated without the SPI with a 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 125
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/0 pins can withstand up to 36 V
