2.00
2012-MAR-29
SD
Amended datasheet version for TMC260 and TMC261
(design and wording). No content changes.
2.01
2012-JUN-07
SD
- Information about power supply sequencing added
(12).
2.02
2012-AUG-01
SD
- Chapter 6.4.2: table layout corrected.
- Information about power supply sequencing
updated.
2.03
2012-AUG-13
SD

2.05
2012-NOV-05
SD
Chapter 8 corrected: The low sensitivity (high sense
resistor voltage, VSENSE=0) brings best and most robust
current regulation, while high sensitivity (low sense
resistor voltage; VSENSE=1) reduces power dissipation in
the sense resistor.

- Layout example updated.
2.10
2016-JUN-06
BD
Added IC Revision TMC260A with improved MOSFETs – see
chapter “Electrical Characteristics” for any differences.
