资 源 简 介

The L298 is an integratedmonolithic circuit in a 15- lead MulTIwatt and PowerSO20 packages. It is a high voltage, high current dual full-bridge driver designedtoacceptstandardTTLlogic levels anddriveinducTIve loads such as relays, solenoids, DC andsteppingmotors. Two enableinputs are providedtoenableor disablethe deviceindependentlyof theinputsignals. The emitters of the lower transistors ofeach bridge are connected togetherand the correspondingexternalterminal can be used for the connecTIonofanexternalsensingresistor.AnaddiTIonalsupply input is provided so that the logic works at a lower voltage.
