Connect both the PGND pins and both the VM pins. Although both the PGND and VM lines are connected internally, both must be connected to provide even lower on-resistance output. 2. Since large currents flow in the VM and PGND lines, these lines should be made thicker, and line impedance reducing capacitors should be inserted in the vicinity of the IC. 3. Since SGND is the ground for the control system, rather than using the same wiring as the PGND line, it is preferable to connect this pin to the CPU ground line. 4. No restriction on priority among applied voltages of VM and VCC. 2/15 12 11 10 9 VCC VM PGND Pin Assignment SGND LV8413GP Application Note 13 PI OUT1 8 14 INA OUT2 7 OUT3 6 OUT4 5 LV8413GP 15 IN4 Top View IN1 VM PGND IN3 IN2 16 1 2 3 4 Recommended Soldering Footprint Specifications Absolute Maximum Ratings at Ta = 25C Parameter Symbol Conditions Ratings Unit Power supply voltage 1 VM max 6 Power supply voltage 2 VCC max 6 Output peak current IO peak Output continuous current 1 Output continuous current 2 V V Outs 1 to 4, t 10msec, ON-duty 20% 600 IO max1 Outs 1 to 4 400 mA IO max2 PI 15 mA Allowable power dissipation Pd max Mounted on a circuit board* 0.7 W Operating temperature Topr -30 to +85 C Storage temperature Tstg -55 to +150 C mA * Specified circuit board : 50.0mm 40.0mm 0.8mm : glass epoxy four-layer board (2S2P) Caution 1) Absolute maximum ratings represent the value 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 Maximum Ratings may damage the device. Maximum Ratings are stress ratings only. Functional operation above the Recommended Operating Conditions is not implied. Extended exposure to stresses above the Recommended Operating Conditions may affect device reliability. 3/15 LV8413GP Application Note Recommended Operating Conditions at Ta = 25C Ratings Parameter Symbol Conditions Unit min typ max Power supply voltage range 1 VM 2.5 5.5 V Power supply voltage range 2 VCC 2.5 5.5 V Logic input voltage range VIN Input frequency fIN 0 VCC+0.3 IN1 to 4, INA V 100 kHz Electrical Characteristics at Ta 25C, VM = 5V, VCC = 3.3V, unless otherwise specified.

The photosensor current is decided by an external resistance value. Input Photo sensor driving INA PI L OFF H ON Overheating protection function (Thermal Shutdown circuit) The overheating protection circuit is built into. OUT1 through OUT4 are turned off when junction temperature Tj exceeds 180C. The value of hysteresis and when it falls, the temperature drives the output again (automatic restoration). The overheating protection circuit doesn't secure protection and the destruction prevention of the set because it becomes operation by the area where ratings Tjmax = 150C of the junction temperature was exceeded. TSD = 180C (typ) TSD = 30C (typ) Low voltage protection function (Low voltage malfunction prevention circuit) When the VCC voltage is as below typical 2.1V in LV8413GP, OUT1 through OUT4 are turned off. When the VCC voltage is as above typical 2.25V, OUT1 through OUT4 are turned on. *When overheating protection function or low voltage protection function is activated, OUT1 through OUT4 are turned off under control of the internal circuit. But the output (PI) of photo sensor driving transistor continues operation. 7/15 LV8431GP Application Note PWM switching waveform example *Please refer to the following test circuit diagram1.
