FEATURES AND BENEFITS DESCRIPTION Voltage Range
2V (1.8V) … 11V DC Working from a single or dual Li-Ion cell or
Battery Operation
min. 2 AA / NiMh cells, or 1-2 Li-Ion cells dual or more AA batteries the TMC7300 is optimally suited for battery operated
1 / 2 DC motors
up to 2A / 2.4A with velocity & torque control equipment. Its two full-bridges allow either
Direct Bridge
control for solenoids, relays, lamps, motors… control of two DC motors, PWM-control of
Single Wire UART
for two-motor torque and velocity control LEDs, or protected standalone peripheral
Standby
<50nA typ. current draw driving, using a polarity signal per half- bridge. Operate up to two DC motors via
Low RDSon
LS 170mΩ & HS 170mΩ (typ.) simple UART control for direction, velocity
Parallel Option
for single DC motor and torque. Integrated power-MOSFETs
Motor Load Feedback
available with internal charge-pump for best-in-class
Full Protection & Diagnostics
RDSon even at low supply voltage, handle
Tiny of QFN 3*3
motor current up to 1.2A per motor with 20 pins 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.
