| www.fairchildsemi.com FAN8200/FAN8200D Low Voltage/Low Saturation Stepping Motor Driver Features * * * * * * * * 3.3V and 5V MPU interface Dual H-bridge drivers for bipolar stepping motor drives Built-in vertical-PNP power transistors Wide supply voltage range(VCC = 2.5V ~ 7.0V) Low saturation voltage (0.4V@ 0.4A) Built-in chip enable function for each bridge Built-in shoot-through current protection Built-in thermal shutdown(TSD) function Description The FAN8200/FAN8200D is a monolithic intergrated circuit designed for two-phase stepping motor drive systems. It has dual H-bridge drivers with vertical-PNP power transistors. Each of the bridges has an independant enable pin, therefore it can be used for other applications as well as stepping motor drive systems. 14-DIP-300 14-SOP-225 1 1 Typical Application * * * * * General low voltage stepping motor driver Floppy disk driver Camera stepping motor driver PC camera or security equipment motion controller Two channel dc motor driver for a digital still camera(DSC) * MPU interfaced general power driver(buffer) Ordering Information Device FAN8200 FAN8200D FAN8200DTF Package 14-DIP-300 14-SOP-225 14-SOP-225 Operating Temp. -20 ~ +75C -20 ~ +75C -20 ~ +75C Rev. 1.0.2 (c)2002 Fairchild Semiconductor Corporation FAN8200/FAN8200D Pin Assignments PGND OUT3 OUT4 PGND 8 7 SGND CE2 VS2 14 13 12 11 10 9 FAN8200/FAN8200D 1 VCC 2 CE1 3 OUT1 4 VS1 5 OUT2 6 IN1 Pin Definitions Pin Number 1 2 3 4 5 6 7 8 9 10 11 12 13 14 Pin Name VCC CE1 OUT1 VS1 OUT2 IN1 SGND PGND IN2 OUT4 VS2 OUT3 CE2 PGND I/O I O O I I O O I Chip enable 1 Output 1 Power supply 1 Output 2 Input 1 Signal ground Power ground Input 2 Output 4 Power supply 2 Output 3 Chip enable 2 Power ground Pin Function Description Logic part supply voltage 2 IN2 FAN8200/FAN8200D Internal Block Diagram 4 VS1 VCC 1 3 50K IN1 6 80K Control Part1 OUT1 50K CE1 2 80K SGND 7 TSD & BIAS 5 OUT2 8 PGND 11 VS2 12 50K IN2 9 80K Control Part2 OUT3 50K CE2 13 10 80K 14 PGND OUT4 3 FAN8200/FAN8200D Absolute Maximum Ratings (Ta = 25C) Parameter Supply voltage Power supply voltage Output voltage Input voltage Peak output current per channel Continuous output current per channel Power dissipation Junction temperture Storage temperature Operating temperature Symbol VCC(MAX) VS(MAX) VOUT(MAX) VIN(MAX) IO(PEAK) IO PDnote TJ TSTG TA Value 9.0 9.0 VS + VCF 7.0 1 0.65 (FAN8200) 0.4 (FAN8200D) 1.0 (FAN8200) 0.6 (FAN8200D) 150 -40 ~ 125 -20 ~ 75 Unit V V V V A A W C C C Notes: 1.
