TB67S549FTG<\/a><\/strong>, with an operating output voltage range from 4.5V to 33V, delivers an operating current of up to 1.2A. It is well suited for a wide range of constant current control stepper motor applications including those found in office automation, commercial and industrial equipment. It is also suited for surveillance cameras and projectors.<\/p>\n\n\n\nThe integrated Advanced Dynamic Mixed Decay (ADMD) system guarantees an efficient PWM current control under all conditions. With the integrated clock interface up to 32 micro steps can be realised.<\/p>\n\n\n\n
Housed in a 4mm x 4mm QFN24 package, the TB67S549FTG occupies only 64% of the mounting area of its predecessor IC and hence saves circuit-board space and costs. Moreover, the internal monitoring circuitry for constant-current control does not require an external current sense resistor, and the charge-pump capacitor is also integrated, thereby further reducing circuit size as well as component count.<\/p>\n\n\n\n
Despite the smaller package size, the ON-resistance of the motor driver output block is at only 1.2\u03a9 (typical), thereby keeping power dissipation low and enabling greater efficiency. In addition, the TB67S549FTG has a power-saving sleep mode that cuts the current consumption to below 1\u03bcA making it widely usable for 12V\/24V power supply applications.<\/p>\n\n\n\n
The TB67S549FTG also integrates a complete set of protection functions, including overcurrent detection, thermal shutdown, and undervoltage lockout.<\/p>\n\n\n\n
Alongside the stepping motor IC, a compact evaluation board is available. Created in partnership with MIKROE, the Stepper 12 Click board is supported by a mikroSDK compliant library and simplifies software development.<\/p>\n","protected":false},"excerpt":{"rendered":"
