Datasheet Driver IC for PPC High Performance, High Reliability 36V 2ch DC Brush Motor Drivers for PPC s etc. BD62220AEFV General Description Key Specifications BD62220AEFV is a built-in 2 channel H-bridge motor Power Supply Voltage Range: 8 to 28 V driver for 2 DC brush motors or 1 stepper motor. This Rated Output Current: 2.0 A driver can facilitate low power consumption by direct Rated Output Current (Peak): 2.8 A PWM or PWM constant current control. There are built in Operating Temperature Range: -25 to +85 C protection circuits in this IC. It is possible to output an Output ON-Resistance: 0.65 (Typ) abnormal detection signal for Wired-OR that notifies each (Total of upper and lower resistors) protection circuit operation, which contributes to set high reliability. Package W(Typ) x D(Typ)x H(Max) Features Single Power Supply Input (rated voltage of 36V) Rated Output Current (peak): 2.0A(2.8A) Low ON-Resistance DMOS Output Forward, Reverse, Brake, Open Power Save Function External PWM Control PWM Constant Current Control (current limit function) Built-in Spike Noise Cancel Function (external noise HTSSOP-B28 filter is unnecessary) 9.70mm x 6.40mm x 1.00mm Driver for 2 DC Brush Motor Driver for 1 Stepper motor FULL STEP, HALF STEP (driving stepper motor) Figure 1 STEP Drive by External DAC (driving stepper motor) Built-in logic input pull-down resistor Typical Application Circuit Cross-conduction Prevention Circuit Output detection signal during abnormal states GND 9 (Wired-OR) Thermal Shutdown Circuit (TSD) 13 PS 16 Over-current Protection Circuit (OCP) IN1A IN1B 17 15 Under Voltage Lock out Circuit (UVLO) FAILA 19 IN2A Over Voltage Lock out Circuit (OVLO) VCC1 20 7 IN2B Ghost Supply Prevention (protects against malfunction OUT1A when power supply is disconnected) 5 Adjacent Pins Short Protection 2 OUT1B VREF1 11 Inverted Mounting Protection 3 Microminiature, ultra-thin and high heat-radiation VREF2 12 RNF1 RNF1S (exposed metal type) HTSSOP-B28 package 4 CR 10 VCC2 22 OUT2A Application 24 Plain Paper Copier (PPC), Multi-function Printer, Laser 27 OUT2B TEST2 Printer, Inkjet Printer, Photo Printer, FAX, Mini Printer and 18 26 RNF2 etc. 25 14 RNF2S TEST1 GND 1 Figure 2.
