6 / 6 page UTCUR0033 LINEAR INTEGRATED CIRCUIT UTC UNISONIC TECHNOLOGIES CO., LTD. 6 QW-R102-023,A Over- current Protection Circuit The over-current protection circuits are built in at the outputs. They protect the IC from being damaged when the load is short-circuited or subjected to an over current condition. This protection circuits perform holdback current limiting. Thermal Protection Circuit A thermal shut down circuit (T.S.D.) is built into the IC to prevent damage due to overheating, Therefore, all the outputs are turned off when the T.S.D. circuit is activated and are turned on when the temperature recedes to the specified level. However, the T.S.D. circuit is only for extreme conditions and the regulator circuit should still be designed for the IC not to exceed TJ(max)=150℃. Grounding It is recommended that every capacitor (bypass and output capacitors) is grounded to PIN3 using single-point connections. Electromagnetic Fields The IC is susceptible to strong electromagnetic fields and may cause malfunction. Therefore, caution should be used when placing it on the PCB. Protection Diodes It is recommended that protection diodes be used when the output is connected to an inductive load. UTC assumes no responsibility for equipment failures that result from using products at values that exceed, even momentarily, rated values (such as maximum ratings, operating condition ranges, or other parameters) listed in products specifications of any and all UTC products described or contained herein. UTC products are not designed for use in life support appliances, devices or systems where malfunction of these products can be reasonably expected to result in personal injury.
