DC Motor 6 x Half briDgE witH ripplE Count

E910.71

Features

Applications

Supply voltage range 6V to 18V

Positioning of HVAC ﬂaps

DC servo systems

6 half bridges configurable to drive 3, 4, or

5 DC motors

Adjustable parameters to drive a high number of

different motor types

General Description

Output current max. 540mA per half bridge

Three independent pulse detectors and counters

Servo control positioning of actuators

Excellent positioning performance

Minimum external components required

SPI for communication with µC

Short circuit protection

The IC features 6 conﬁgurable half bridges to drive up to

3 DC motors simultaneously or up to 5 motors sequen-

tially. 3 independent pulse detection circuits convert

the commutation current of the motors into countable

digital signals especially for positioning of HVAC ﬂap

actuators.

Overtemperature protection

Over and undervoltage detection

Diagnostic data via SPI

Operating temperature range -40°C to +85°C

QFN 7x7 32Ld package

SOIC 28 package

Via an SPI a µC sends motor address, direction, and

pulse count command to the device. The corresponding

motor will then be driven to the desired position, and

the actual number of counts is sent back to the µC.

Diagnostic data such as overcurrent, overtemperature,

and motor stall is also transmitted via the SPI. An open

drain low side output indicates when a required motor

position is reached or diagnostic data is available. ICs

can be connected in a daisy chain.
