TMC249A-SA

Product name
TMC249A-SA
Model
TMC249A-SA
Package
SOP28
Product overview
The TMC249 / TMC249A(1) is a dual full bridge driver IC for bipolar stepper motor control applications. The TMC249 is implemented in HVCMOS technology and directly drives eight external low RDS-ON high efficiency MOSFETs. It supports currents in excess of 4000 mA coils.
Detailed description

More than using 4000 mA 8 external MOS transistors (eg 2.8A RMS)

Sensor stall detection stall protection and load measurement integration

SPI control with easy-to-use 12-bit protocol or external analog/digital signals

Short circuit, over voltage and over temperature protection

Overcurrent status flag, open load, over temperature, temperature warning, undervoltage

Integrated 4-bit DAC allows up to 16 micro-micro via SPI, by simulating any resolution

Control

Smooth motor running hybrid attenuation characteristics

Slope control user programmable to reduce electromagnetic radiation

Programmable by a capacitor or external clock frequency

Current control allows operation of cool motors and drives

7V to 34V motor power supply voltage (type A)

External drivers can be added to increase the motor voltage and higher current (eg 50V, 5A)

Operation for digital part 3.3V or 5V

Low power consumption through low RDS-ON power stage

Available in standby and shutdown modes

SO28 or chip size MLF package selection
