Load 1 No. 5641-4/6 LC4105V Power Supply Circuits Keep the impedance of the VSS and VSS1 lines as low as possible. Connect a large electrolytic capacitor across the VDD1 and VSS1 pins and close to the IC. Wherever possible, keep the grounds for the power supply circuits and the signal circuits separate and connect the two at a single point. Notes on Power-Supply Voltage Application This IC has two power supply systems: VDD (VDD1) and VCC, and requires that applications observe the notes provided here when applying or removing these voltages. In particular, if the VDD (VDD1) system power-supply voltage becomes higher than the VCC system voltage while the VCC system voltage is not yet established (i.e. is less than VCCmin), excessive currents may flow and the IC may be destroyed. To prevent destruction of the IC due to this phenomenon, applications must, basically, follow the sequence described in item 1 below when turning the power supplies on or off. 1. When turning the power on, first apply the VCC voltage (bring this voltage to a value above VCCmin), and then apply the VDD voltage. When turning the power off, first drop the VDD voltage, and, after VDD is below VCCmin, then drop the VCC voltage. Power-supply voltage VDD,VDD1 VCC Time No. 5641-5/6 LC4105V However, there are many cases where it is not possible to control the power-supply voltage on/off sequence. This IC is actually capable of supporting the on/off sequence described in item 2 below. 2. If VDD (VDD1) and VCC are turned on and off at essentially the same time, the difference between VDD and VCC (e.g. the distance in the figure marked as ∆0.5 V) must be held to be under 0.5 V while VCC is less than or equal to 3.0 V. Power-supply voltage VDD,VDD1 VCC Time Another point is that a certain amount of time is required to stabilize the VCC system when VCC is first applied and the IC is easily destroyed during this period. Inversely, when the power is removed, the VCC system state is easily retained and as a result the device cannot be destroyed easily. In actual use, one can consider there to be a certain amount of margin for removing the VDD (VDD1) voltage even after VCC has already been dropped. However, this margin varies with sample-to-sample variations in the IC itself and with the details of the application circuit, and careful analysis and consideration of the actual usage conditions is required to assure that the IC will not be destroyed if the sequences in items 1 or 2 are not observed. 3. Note that when power is turned off and then immediately turned back on again, many circuit designs may fail to meet the conditions for the sequences described in items 1 and 2 above. Be sure to take this into account when designing applications that use this IC. ■ No products described or contained herein are intended for use in surgical implants, life-support systems, aerospace equipment, nuclear power control systems, vehicles, disaster/crime-prevention equipment and the like, the failure of which may directly or indirectly cause injury, death or property loss. ■ Anyone purchasing any products described or contained herein for an above-mentioned use shall: ➀ Accept full responsibility and indemnify and defend SANYO ELECTRIC CO., LTD., its affiliates, subsidiaries and distributors and all their officers and employees, jointly and severally, against any and all claims and litigation and all damages, cost and expenses associated with such use: ➁ Not impose any responsibility for any fault or negligence which may be cited in any such claim or litigation on SANYO ELECTRIC CO., LTD., its affiliates, subsidiaries and distributors or any of their officers and employees jointly or severally. ■ Information (including circuit diagrams and circuit parameters) herein is for example only; it is not guaranteed for volume production.
