Ordering number : ENA2176A LV52204MU Bi-CMOS IC LV52204MU Specifications Absolute Maximum Ratings at Ta = 25C Parameter Symbol Conditions Ratings Unit Maximum supply voltage V max V 5.5 V CC CC Maximum pin voltage1 V1 max SW 40 V Maximum pin voltage2 V2 max Other pin 5.5 V Allowable power dissipation Pd max Ta = 25C *1 2.05 W Operating temperature Topr -30 to +85 C Storage temperature Tstg -55 to +125 C *1 Mounted on a specified board: 70mm50mm1.2mm (4 layer glass epoxy) Caution 1) Absolute maximum ratings represent the values which cannot be exceeded for any length of time. Caution 2) Even when the device is used within the range of absolute maximum ratings, as a result of continuous usage under high temperature, high current, high voltage, or drastic temperature change, the reliability of the IC may be degraded. Please contact us for the further details. Stresses exceeding those listed in the Maximum Ratings table may damage the device. If any of these limits are exceeded, device functionality should not be assumed, damage may occur and reliability may be affected. Recommendation Operating Condition at Ta = 25 C Parameter Symbol Conditions Ratings Unit Supply voltage range1 V op V 2.7 to 5.5 V CC CC PWM frequency Fpwm PWM MODE 300 to 100k Hz Functional operation above the stresses listed in the Recommended Operating Ranges is not implied. Extended exposure to stresses beyond the Recommended Operating Ranges limits may affect device reliability.
