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 under-
voltage on VPWR, short to ground and short to VPWR for each output, open load, temper-
ature 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/
s to more than 16 V/
s 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 ap-
plications
• Can be operated without the SPI with a default slew rate of 2.0 V/
s 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 noti-
fication in H-Bridge mode
• Wide operating range: 5.0 V to 28 V operation
• Low R
DS(on)
integrated MOSFETs: Maximum of 125 m
(T
J
= 150 °C) for each MOSFET
• Internal protection for overtemperature, undervoltage and short-circuit by signaling the er-
ror condition and disabling the outputs
• I/0 Pins can withstand up to 36 V
