Description

Features

MC33HB2000

The MC33HB2000 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 electromagnetic interference

(EMI) and thermal performance optimization

• Four selectable current limits via the SPI: 5.4 A, 7.0 A,

8.8 A, 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 RDS(on) integrated metal‑oxide‑semiconductor

field‑effect transistors (MOSFETs): Maximum of

235 mΩ (TJ = 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
