Frequently Asked Questions
What is the maximum operating voltage range?
The device supports a single supply voltage of 4V to 28V and split supplies ranging from ±2V to ±14V.
How much power can the unit dissipate at room temperature?
At T = 85°C, the maximum power dissipation is 1W (total ambient).
What safety measure prevents overheating?
The L2726 features a thermal shutdown mechanism, which triggers when the junction temperature reaches 150°C.
What common environmental protection feature is included?
It includes an S$_{O}$ (clamp diode) for overvoltage protection rated at 20V (12 + 4 + 4).
Is this chip suitable for low-power motor applications?
Yes, it performs well in driving inductive loads, making it useful as a servo amplifier or power booster.
