Ordering number : EN7233A LB1936V Monolithic Digital IC 1-2 Phase Excitation Stepper Motor Driver http://onsemi.com Overview The LB1936V is a 2-phase bipolar drive stepper motor driver IC that supports low-voltage drive. The LB1936V's miniature package and minimal number of external components reduces the required mounting area. It also provides high-efficiency motor drive and can reduce circuit current consumption. Since it provides a current detection pin and supports PWM control input, it can be used to implement current chopper control at the system level. The LB1936V is optimal for the stepper motor drive in scanners, digital cameras, and printers. Features • Low saturation voltage forward/reverse motor driver (VO sat = 0.25V at IO = 200mA) • Two H-bridge channels • Wide usable voltage range (Allowable voltage range : 2.5V to 9.5V, absolute maximum rating : 10.5V) • Supports PWM input (Low power consumption can be achieved in slow delay mode that uses IN1/IN2 = H/H logic.) • Motor (coil) current detection pin • Built-in thermal shutdown circuit • Miniature package (SSOP16 : 225mil) Specifications Absolute Maximum Ratings at Ta = 25°C Parameter Maximum supply voltage Maximum output voltage Maximum input voltage Ground pin source current Allowable power dissipation Symbol VCC max VS max VOUT max VIN max IGND max Pd max Conditions Per channel When mounted on a circuit board * Operating temperature Storage temperature Topr Tstg * Specified circuit board : 114.3 × 76.1 × 1.6mm3, glass epoxy Ratings -0.3 to +10.5 -0.3 to +10.5 VS+ VSF -0.3 to +8.0 800 740 -20 to +85 -40 to +150 Unit V V V V mA mW °C °C Stresses exceeding Maximum Ratings may damage the device. Maximum Ratings are stress ratings only. Functional operation above the Recommended Operating Conditions is not implied. Extended exposure to stresses above the Recommended Operating Conditions may affect device reliability.
