2.04
2012-AUG-01
SD

2.05
2012-AUG-13
SD
- Figure 11.2 (undervoltage reset timing) new
2.06
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.
