PWM method CLK-IN bipolar stepping motor driver
The TB62269FTG is a two-phase bipolar stepping motor driver using a PWM chopper.
Fabricated with the BiCD process, the TB62269FTG is rated at 40 V/1.8 A .
The internal voltage regulator allows control of the motor with a single
VM power supply.
Features
• Drive control is possible in a bipolar stepping motor at 1 chip.
• PWM controlled constant-current drive
• Allows full, half and quarter ,1/8,1/16,1/32 step resolutions.
P-WQFN48-0707-0.50-003
• Low on-resistance of output stage transistor is low by using BiCD process.
• High Voltage and current (For specification, please refer to absolute
Weight:0.14g(Typ.)
maximum ratings and operation ranges)
• Thermal shutdown (TSD)、over-current shutdown (ISD),
• and power-on reset of VM power supply (POR)
• Built-in regulator allows the TB62269FTG to function with only VM power supply.
• Able to customize PWM signal frequency by external resistance/capacitor.
