LV8012T

Ordering number : EN7190A LV8012T Overview Bi-CMOS LSI Forward/Reverse Motor Driver LV8012T 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 Supply voltage (For load) Supply voltage (For control) Output current Input voltage Allowable power dissipation Operating temperature Storage temperature * : Mounted on a substrate : Symbol VM max VCC max IO max VIN max Pd Topr Tstg 30×50×1.6mm3, glass epoxy board * Mounted on a substrate t ≤ 100ms Conditions Ratings -0.5 to 7.5 -0.5 to 6.0 1.4 -0.5 to VCC+0.5 800 -20 to +75 -55 to +150 Unit V V A V mW °C °C 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.).
