Description

TLE 5250 is a monolithic IC in Smart Power technology for controlling and regulating the motor current in one phase of a bipolar stepping motor. There are other applications in driving DC motors and inductive loads that are operated on constant current.

The device has TTL-compatible logic inputs, includes a H-bridge with integrated, fast free-wheeling diodes plus dynamic limiting of the motor current by a chopper mode. The nominal current can be set continuously by a control voltage. Microstep mode can be produced by applying a sinusoidal control voltage. Two TLE 5250s, with a minimum of
external circuitry and a single supply voltage, form a complete system - that can be driven direct by an MC- for two-phase, bipolar stepping motors with output current of up to 2.5 A per phase. The outputs of the TLE 5250 are internally protected against shorted to ground, supply voltage and shorted load. The output stages are also disabled by undervoltage and overtemperature. All fault functions can be detected by the internal diagnostics, which can be read out serially.
