Introduction
The DRV8837C customer EVM is a platform built around the DRV8837C device which is a single H-bridge
brushed DC-motor driver. This device drives one brushed DC motor with up to 1 A of output current and is
controlled using a PWM (IN/IN) input interface.
The EVM includes an MSP430G2131 microcontroller to supply all required drive signals for dual-direction
motor rotation. This EVM also has an onboard regulator to supply 3.3 V to both the MCU and the logic
supply of the DRV8837C device.
Two headers are included for simple direction and nSLEEP control. An easily adjustable potentiometer is
also populated on the board to allow for simple motor speed adjustment. Because the DRV8837C device
can operate with small VM voltages, the EVM includes a USB-Mini type B connector which can be used
as a 5-V supply for the EVM.
2
Connectors
The DRV8837C EVM allows connections to the VM (motor voltage) power rail through a three-pin header
(JP2). The center pin of this three-pin test clip is floating and intended to help the user differentiate
between the motor and power connection. A test clip labeled VM is available to probe the input power rail.

Drive Configuration
The DRV8837C EVM can control the speed and direction of the motor by varying the signals supplied to
the IN1 and IN2 pins on the DRV8837C device. The MSP430G2131 device varies the duty cycle of the
PWM signal supplied to the driver based on the voltage measured between the 10-kΩ potentiometer R7.
The direction can be varied using the jumper installed on JP1. Table 2 lists the logic for this jumper.
NOTE: The direction that the motor spins in is dependent on the polarity of the motor lead
connections to the bridge connections. Refer to the data sheet of the motor to determine
which motor terminal should be connected to each driver output.

Speed Control Potentiometer (R7)
To control the speed of the motor a 10-kΩ potentiometer is connected to an ADC on the MSP430G2131
device. When the pot is all the way to the left, the PWM signal supplied to the driver will be 0%, and when
it is all the way to the right, the signal will be 100% which is denoted by the 0% and 100% labels next to
the potentiometer.

endorsement thereof. Use of such information may require a license from a third party under the patents or other intellectual property of the
third party, or a license from TI under the patents or other intellectual property of TI.
Reproduction of significant portions of TI information in TI data books or data sheets is permissible only if reproduction is without alteration
and is accompanied by all associated warranties, conditions, limitations, and notices. TI is not responsible or liable for such altered
documentation. Information of third parties may be subject to additional restrictions.
Resale of TI components or services with statements different from or beyond the parameters stated by TI for that component or service
voids all express and any implied warranties for the associated TI component or service and is an unfair and deceptive business practice.
TI is not responsible or liable for any such statements.
Buyer acknowledges and agrees that it is solely responsible for compliance with all legal, regulatory and safety-related requirements
concerning its products, and any use of TI components in its applications, notwithstanding any applications-related information or support
that may be provided by TI. Buyer represents and agrees that it has all the necessary expertise to create and implement safeguards which
anticipate dangerous consequences of failures, monitor failures and their consequences, lessen the likelihood of failures that might cause
harm and take appropriate remedial actions. Buyer will fully indemnify TI and its representatives against any damages arising out of the use
of any TI components in safety-critical applications.
In some cases, TI components may be promoted specifically to facilitate safety-related applications. With such components, TI’s goal is to
help enable customers to design and create their own end-product solutions that meet applicable functional safety standards and
requirements. Nonetheless, such components are subject to these terms.
No TI components are authorized for use in FDA Class III (or similar life-critical medical equipment) unless authorized officers of the parties
have executed a special agreement specifically governing such use.
Only those TI components which TI has specifically designated as military grade or “enhanced plastic” are designed and intended for use in
military/aerospace applications or environments. Buyer acknowledges and agrees that any military or aerospace use of TI components
which have not been so designated is solely at the Buyer's risk, and that Buyer is solely responsible for compliance with all legal and
regulatory requirements in connection with such use.
TI has specifically designated certain components as meeting ISO/TS16949 requirements, mainly for automotive use. In any case of use of
non-designated products, TI will not be responsible for any failure to meet ISO/TS16949.
