4 / 8 page SA1582 HANGZHOU SILAN MICROELECTRONICS CO.,LTD REV:1.2 2006.06.26 Http: www.silan.com.cn Page 4 of 8 FUNCTION DESCRIPTION 1. LOGIC INPUT & OUTPUT TABLE Input Output Pin4 Pin5 Pin2 Pin8 Motor Low Low *Low *Low Brake High Low High Low Forward Low High Low High Reverse High High *Low *Low Brake INPUT High is above 2.0V. INPUT Low is below 0.7V. * Low: all power TRs are off-state. But internal bias makes output voltage low state. 2. DRIVE OUTPUT CIRCUIT V1 M V2 PVCC Q2 Q5 R1 R2 RL VO1 VO2 Q3 Q6 Q1 Q4 When one input pin is “H”and another is “L”, and pin3 connect to GND with a zener diode; Vzd is the voltage between pin3 and GND. V1 = Vzd + 2Vbe ≅ 7.4V + 2 * 0.7V = 8.8V V2 = Vbe + Vsat ≅ 0.2V + 0.7V = 0.9V VO1 = V1 - VBEQ1 - VBEQ2 VO2 = VQ6SAT VO = VO1 - VO2 = V1 - VBEQ1 - VBEQ2 - VQ6SAT IRL = (VO1 - VO2) / RL |
