When the AN8814SB is use, take into account the following cautions and follow the power dissipation characteristic curve. 1. Load current IP1 flowing into load RL1, RL2 is supplied through pin 20. | V18 -V17 | | V16 -V15 | IP1 = + RL1 RL2 2. Load current IP2 flowing into load RL3, RL4 is supplied through pin 9. | V14 -V13 | | V12 -V11 | IP2 = + RL3 RL4 3. Dissipation increase (PD) inside the IC (power output stage) caused by loads RL1, RL2, RL3 and RL4 is as follows: | V18 -V17 | | V16 -V15 | PD = (PVCC1 - | V18 -V17 |) x + (PVCC1 - | V16 - V15 |) + RL1 RL2 | V14 -V13 | | V12 -V11 | = (PVCC2 - | V14 -V13 |) x + (PVCC2 - | V12 - V11 |) x RL3 RL4 4. Dissipation increase (PS) inside the IC (signal block supplied from pin 7) caused by loads RL1, RL2, RL3 and RL4 comes roughly as follows: V V PS = 3 x { 1 x (2 x SVCC + | V18 -V17 |) + 2 x (2 x SVCC + | V16 -V15 |) R1 R2 V3 V4 + x (2 x SVCC + | V14 -V13 |) + x (2 x SVCC + | V12 -V11 |)} R3 R4 5. Dissipation increase in a driver operating mode is PD + PS . 6. Allowable power dissipation without load (PD1) can be found as follows: PD1 = SVCC x ISVCC + PVCC1 x IPVCC1 + PVCC2 x IPVCC2 7. Allowable power dissipation in a load operating mode (PD) comes roughly as follows: PD = PD1 + PD + PS
