Product Summary

The L6219 is a bipolar monolithic integrated circuit intended to control and drive both winding of a bipolar stepper motor or bidirectionally control two DC motors. The L6219 with a few external components form a complete control and drive circuit for LS-TTL or microprocessor controlled stepper motor system. The L6219 power stage is a dual full bridge capable of sustaining 46V and including four diodes for current recirculation.

Parametrics

L6219 absolute maximum ratings: (1)VS, Supply Voltage: 50 V; (2)Io, Output Current (peak): ±1A; (3)Io, Output Current (continuous): ±0.75 A; (4)VSS, Logic Supply Voltage: 7 V; (5)VIN, Logic Input Voltage Range: -0.3 to +7 V; (6)Vsense, Sense Output Voltage: 1.5 V; (7)TJ, Junction Temperature: +150℃; (8)Top, Operating Temperature Range: -20 to +85℃; (9)Tstg, Storage Temperature Range: -55 to +150℃.

Features

L6219 features: (1)able to drive both windings of bipo-lar stepper motor; (2)output current up to 750mA each winding; (3)wide voltage range 10V to 46V; (4)half-step, full-step and microstepp-ing mode; (5); (6)internal pwm current control; (7)low output saturation voltage; (8)designed for unstabilized motor supply voltage; (9)internal thermal shutdown.
