Notes

1. Soldering temperature limit is for 10 seconds maximum duration. Not designed for immersion soldering. Exceeding these limits may cause

malfunction or permanent damage to the device.

2. With 2.0 in2 of copper headsink.

3. ESD1 testing is performed in accordance with the Human Body Model (CZAP = 100 pF, RZAP = 1500 Ω).

4. With no additional heatsinking.

5. Maximum quiescent power dissipation is 0.25 W.

6. 12 V ≤ VB+ ≤ 32 V and -20°C ≤ TJ ≤ 145°C unless otherwise noted.
