DESCRIPTION
Working from a single or dual Li-Ion cell or
dual or more AA batteries the TMC7300 is
optimally suited for battery operated
equipment. Its two full-bridges allow either
control of two DC motors, PWM-control of
LEDs, or protected standalone peripheral
driving, using a polarity signal per half-
bridge. Operate up to two DC motors via
simple UART control for direction, velocity
and torque. Integrated power-MOSFETs
with internal charge-pump for best-in-class
RDSon even at low supply voltage, handle
motor current up to 1.2A per motor
continuously, or the double current in
parallel connection. Together with a tiny
standby current, this guarantees a long
battery life. Protection and diagnostic
features support robust and reliable
operation. This advanced driver ensures
efficient and reliable operation for cost-
effective and highly competitive solutions.

APPLICATION EXAMPLES: SIMPLE SOLUTIONS HIGHLY EFFECTIVE
The TMC7300 scores with a high power density using integrated power MOSFETs and a complete
integrated DC motor control logic, to control velocity and limit torque, or for torque controlled
operation. It covers a wide spectrum of applications from battery systems to embedded applications
with up to 2A (2.4A) current per motor. Extensive support enables rapid design cycles and fast time-to-
market with highly competitive products.

A CPU operates the driver via its UART
interface. It configures motor direction
and velocity as well as current limit,
and accesses diagnostic information
via the UART interface. The TMC7300
takes care for voltage and current
regulation and overcurrent protection.
With single motor operation, output
current is increased and power
dissipation is reduced.

The TMC7300 acts a peripheral driver
for a low-voltage application. It drives
resistive loads, like a LED, or inductive
loads like motors or solenoids. It
offers up to 2A peak output current
while adding protection features.
The TMC7300-EVAL is part of
TRINAMICs universal evaluation board
system which provides a convenient
handling of the hardware as well as a
user-friendly software tool for
evaluation. The TMC7300 evaluation
board system consists of three parts:
STARTRAMPE (base board), Eselsbrücke
(connector board with test points), and
TMC7300-EVAL.
