P-SIP-15-1
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 IC 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.
