L6208QTR Detalles de producto

Description

The L6208Q device is a DMOS fully integrated stepper motor driver with non-dissipative overcurrent protection, realized in BCDmultipower technology, which combines isolated DMOS power transistors with CMOS and bipolar circuits on the same chip. The device includes all the circuitry needed to drive a two-phase bipolar stepper motor including: a dual DMOS full bridge, the constant OFF time PWM current controller that performs the chopping regulation, and the phase sequence generator that generates the stepping sequence. Available in a VFQFPN48 7 x 7 mm package, the L6208Q features a non dissipative overcurrent protection on the high-side Power MOSFETs and thermal shutdown.



Features

• Operating supply voltage from 8 to 52 V

• 5.6 A output peak current

• RDS(on) 0.3 Ω typ. value at Tj = 25 °C

• Operating frequency up to 100 kHz

• Non-dissipative overcurrent protection

• Dual independent constant tOFF PWM current controllers

• Fast/slow decay synchronous rectification

• Fast decay quasi-synchronous rectification

• Decoding logic for stepper motor full and half step drive

• Cross conduction protection

• Thermal shutdown

• Undervoltage lockout

• Integrated fast freewheeling diodes



Application

• Bipolar stepper motor
