CAT4106
ABSOLUTE MAXIMUM RATINGS
RECOMMENDED OPERATING CONDITIONS
Typical application circuit with external components is shown on page 1.
RECOMMENDED EN/PWM TIMING
For 3.0 ≤ VIN ≤ 5.5V, over full ambient temperature range -40 to +85ºC.
Notes:
(1) Stresses above those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings
