Ordering number : ENA2014 Monolithic Digital IC Two-channel H-Bridge Driver LB1973JA Overview The LB1973JA is a two-channel H-bridge driver that supports for low saturation draive operation. It is optimal for H-bridge drive of stepping motors (AF and zoom) in portable equipment such as camera cell phones. Features • Two-channel H-bridge driver • 2ch simultaneous connection is possible • Parallel input interface • 2 phase excitation, 1-2 phase excitation drive are possible • The range of the operation voltage is wide.(1.8V to 7.5V) • Built-in thermal protection Specifications Absolute Maximum Ratings at Ta = 25°C Parameter Maximum supply voltage Output voltage Symbol Conditions VCC max VOUT max Ratings Unit -0.3 to +8.0 V - VSF to VCC+VSF V Input voltage VIN max -0.3 to +8.0 Spark killer Di order direction electric ISF max 1000 Ground pin source current Allowable power dissipation IGND Per channel Pd max *Mounted on a bord V mA 1000 mA 800 mW Operating temperature Topr -20 to +85 °C Storage temperature Tstg -40 to +150 °C * Mounted on a Specified board : 114.3mm×76.1mm×1.6mm, glass epoxy Caution 1) Absolute maximum ratings represent the value which cannot be exceeded for any length of time. Caution 2) Even when the device is used within the range of absolute maximum ratings, as a result of continuous usage under high temperature, high current, high voltage, or drastic temperature change, the reliability of the IC may be degraded. Please contact us for the further details.
