System Motor Driver IC for CD/DVD players
5ch System Moter Driver
BD8203EFV
No.10011EAT02
Description BD8203EFV is 5ch system motor driver for CD/DVD. A linear BTL method can be adopted for all 5ch and a low noise be designed. Built-in 5V regulator, a changeable regulator, and a general-purpose operational amplifier , and it is the best for the system design for car audio. Features 1) Linear BTL method is adopted for the actuator driver and the DC motor driver and a low noise is achieved. 2) Loading driver 1CH 3) Built-in regulator 2CH (1ch output changeability) 4) MUTE function and Standby function 5) Built-in general-purpose operational amplifier 1CH 6) Built-in internal operational amplifier for the voltage detection between driver outputs and for Vc standard Applications Car Audio Absolute Maximum Ratings Parameter Power supply voltage Input terminal voltage1 Input terminal voltage2 Output terminal voltage Operating temperature range Storage temperature Junction temperature

Noise measures The cause of PWM driver's noise is the following. A.Noise from Vcc and GNT line B.Radiation noise
Technical Note
~Measures of A~ Because a large current by the PWM output flows, driver's power supply (PVCC) and GNT line (PGNT) lower the wiring impedance. Please separate with the power supply line of other devices in the root without common impedance, and connect it in another line. Please stabilize it strongly for power supply pin (PVCC1,PVCC2,PREVCC) of drivers and GNT pin (PVCC) by the electrolytic capacitor that ESR is low. Please apply the ceramic capacitor with a high frequency characteristic to the root of IC.

Notes for use
Technical Note
1.Absolute maximum ratings We are careful enough for quality control about this IC. So, there is no problem under normal operation, excluding that it exceeds the absolute maximum ratings. However, this IC might be destroyed when the absolute maximum ratings, such as impressed voltages or the operating temperature range, is exceeded, and whether the destruction is short circuit mode or open circuit mode cannot be specified. Please take into consideration the physical countermeasures for safety, such as fusing, if a particular mode that exceeds the absolute maximum rating is assumed. 2.Reverse polarity connection Connecting the power line to the IC in reverse polarity (from that recommended) will damage the part. Please utilize the direction protection device as a diode in the supply line and motor coil line. 3.Power supply line Due to return of regenerative current by reverse electromotive force of external coil, using electrolytic and ceramic suppress filter capacitors (0.1F) close to the IC power input terminals (Vcc and GNT) are recommended. Please note the electrolytic capacitor value decreases at lower temperatures and examine to dispense physical measures for safety. 4.GNT line Please keep the SGNT, PGNT,1, PGNT2 line the lowest potential always, and check the GNT voltage when transient voltages are connected to the IC. 5.Thermal design Do not exceed the power dissipation (Pd) of the package specification rating under actual operation, and please design enough temperature margins. This product has exposed the frame to the back side of the package, but please note that it is assumed to use heat radiation efficiency by the heat radiation for this part. Please take the heat radiation pattern on not only the surface of the substrate but also the back of the substrate widely. 6.Short circuit mode between terminals and wrong mounting Do not mount the IC in the wrong direction and displacement, and be careful about the reverse-connection of the power connector. Moreover, this IC might be destroyed when the dust short the terminals between them or GNT. ( The outputs of CH1(pin2,3) have NO protection circuit. So please especially be careful about them.) 7.Radiation Strong electromagnetic radiation can cause operation failures. 8.ASO (Area of Safety Operation) Do not exceed the maximum ASO and the absolute maximum ratings of the output driver. 9.TSD (Thermal Shut-Down) The TSD is activated when the junction temperature (Tj) exceeds Tjmax, and the output terminal is switched to OPEN. The guarantee and protection of set are not purpose. Therefore, please do not use this IC after TSD circuit operates, nor use it for assumption that operates the TSD circuit. 10.Capacitor between output and GNT If a large capacitor is connected between the output and GNT, this IC might be destroyed when Vcc becomes 0V or GNT, because the electric charge accumulated in the capacitor flows to the output. Please set said capacitor to smaller than 0.1F. 11.About the capacitor between the outputs The output current increases compared with the change between the outputs when the capacitor is connected between the driver outputs. Therefore, please do measures such as putting bypass capacitor (0.1uF) in a nearest pin of power supply (PVCC) and GNT(PGNT) of this IC as the route of the output current. Please decide the capacity value after confirming there is no problem in various characteristics enough, it is possible to pull out capacity at the low temperature happening to the electrolytic capacitor more than the capacity value of the capacitor between the outputs. 12. Inspection by the set circuit board The stress might hang to IC by connecting the capacitor to the terminal with low impedance. Then, please discharge electricity in each and all process. Moreover, when attaching or detaching from jig in the inspection process, please turn off the power before mounting the IC, and turn on after mounting the IC, and vice versa. In addition, please take into consideration the countermeasures for electrostatic damage, such as giving the earth in assembly process, transportation or preservation. 13. Input terminal + This IC is a monolithic IC, and has P isolation and P substrate for the element separation. Therefore, a parasitic PN junction is firmed in this P-layer and N-layer of each element. For instance, the resistor or the transistor is connected to the terminal as shown in the figure below. When the GNT voltage potential is greater than the voltage potential at Terminals A on the resistor, at Terminal B on the transistor, the PN junction operates as a parasitic diode. In addition, the parasitic NPN transistor is formed in said parasitic diode and the N layer of surrounding elements close to said parasitic diode. These parasitic elements are formed in the IC because of the voltage relation. The parasitic element operating causes the interference of circuit operation, then the wrong operation and destruction. Therefore, please be careful so as not to operate the parasitic elements by impressing to input terminals lower voltage than GNT (P substrate). Please do not apply the voltage to the input terminal when the power-supply voltage is not impressed. Moreover, please impress each input terminal lower than the power-supply voltage or equal to the specified range in the guaranteed voltage when the power-supply voltage is impressing.

14. Earth wiring pattern If small signal GNT and large current GNT exist, disperse their pattern. In addition, for voltage change by pattern wiring impedance and large current not to change voltage of small signal GNT, each ground terminal of IC must be connected at the one point on the set circuit board. As for GNT of external parts, it is similar to the above-mentioned.
