Product Summary

The L298HN is a dual full-bridge driver. The L298HN is an integratedmonolithic circuit in a 15- lead Multiwatt and PowerSO20 packages. The L298HN is a high voltage, high current dual full-bridge driver designedto acceptstandardTTLlogic levels anddrive inductive loads such as relays, solenoids, DC and steppingmotors. Two enableinputs are providedto enableor disablethe deviceindependentlyof theinput signals. The emitters of the lower transistors of each bridge are connected togetherand the correspondingexternal terminal can be used for the connectionofanexternalsensingresistor. Anadditional supply input is provided so that the logic works at a lower voltage.

Parametrics

L298HN absolute maximum ratings: (1)VS Power Supply 50 V; (2)VSS Logic Supply Voltage: 7 V; (3)VI,Ven Input and Enable Voltage: –0.3 to 7 V; (4)IO Peak Output Current (each Channel): 3A; (5)Vsens Sensing Voltage: –1 to 2.3 V; (6)Ptot Total Power Dissipation (Tcase = 75°C): 25 W; (7)Top Junction Operating Temperature: –25 to 130 °C; (8)Tstg, Tj Storage and Junction Temperature: –40 to 150 °C.

Features

L298HNZ features: (1)operatingsupply voltageup to 46 v; (2)total dc current up to 4 A; (3)lowsaturation voltage; (4)overtemperature protection logical 0 input voltage up to 1.5 v (highnoise immunity).
