Ordering number : ENA1134 Bi-CMOS LSI LV8014T Forward/Reverse Motor Driver Overview LV8014T is a 2ch forward/reverse motor driver IC using D-MOS FET for output stage. As MOS circuit is used, it supports the PWM input. Its features are that the on resistance (0.75Ω typ) and current dissipation are low. It also provides protection functions such as heat protection circuit and reduced voltage detection and is optimal for the motors that need high-current. Functions • 2ch forward/reverse motor driver • Possible to respond to 3V control voltage and 6V motor voltage device • Low power consumption • Low-temperature resistance 1.2Ω • Built-in charge pump circuit • Built-in low voltage reset and thermal shutdown circuit • Four mode function forward/reverse, brake, stop. • Compact TSSOP-24 package Specifications Absolute Maximum Ratings at Ta = 25°C, SGND = PGND = 0V Parameter Symbol Supply voltage (For load) Supply voltage (For control) Conditions Unit -0.5 to 7.5 VCC max -0.5 to 6.0 V 1.4 A 2.5 A IO max t ≤ 100ms Output peak current IO max2 t ≤ 10ms Input voltage VIN max Allowable dissipation Pd max Output current Ratings VM1, 2 max -0.5 to VCC+0.5 * Mounted on a substrate 800 V V mW Operating temperature Topr -20 to +75 °C Storage temperature Tstg -55 to +150 °C * : Mounted on a substrate : 30×50×1.6mm3, glass epoxy board Any and all SANYO Semiconductor Co.,Ltd. products described or contained herein are, with regard to "standard application", intended for the use as general electronics equipment (home appliances, AV equipment, communication device, office equipment, industrial equipment etc.).
