The built-in 0.4\u03a9 MOSFETs eliminate the need for external transistors. The device supports microstepping from full step to 1\/16 step via three mode-select pins. A simple clock-direction interface allows easy MCU control. The PWM chopper regulates winding current with the chopping frequency set by an external resistor. Protection features include thermal shutdown (TSD) at 160\u00b0C with configurable auto-recovery or latch mode, overcurrent detection (ISD) at 6.5A, and undervoltage lockout (UVLO). The HZIP-25 through-hole package provides excellent thermal dissipation with a tab for heatsink mounting.","working_principle":"The TB6600HG uses a PWM chopper scheme to regulate current through the two motor windings. The CLK pin receives step pulses; each rising edge advances the internal indexer by one microstep. The indexer generates the two sinusoidal phase current targets according to the selected microstep resolution. The PWM chopper compares the actual winding current (sensed through the internal MOSFETs) with the target: when the current exceeds the target, the high-side MOSFET turns off for the chopper off-time, allowing the current to decay through the low-side MOSFET. The off-time is set by the external Rosc resistor. The direction of rotation is controlled by the CW\/CCW pin. The ENABLE pin enables or disables all outputs, and the RESET pin returns the indexer to the initial position (home state). The TSD circuit monitors junction temperature; when it exceeds 160\u00b0C, all outputs are disabled and the ALERT pin goes low. The LATCH\/AUTO pin selects whether TSD recovery is automatic (when temperature drops to 90\u00b0C) or requires an ENABLE toggle. The ISD circuit monitors current through each MOSFET; if overcurrent is detected (>6.5A), all outputs are immediately disabled until ENABLE is toggled. The UVLO circuit disables outputs when VCC drops below 8V.","pin_description":"\n

        TB6600HG is a 4.5A\/42V bipolar stepper motor driver from Toshiba in HZIP-25. The TB6600FTG is the surface-mount version. The TB67S109AFTG provides 3.5A with 1\/128 microstepping in smaller QFN-48. The DRV8825 from TI offers 2.5A\/32V with 1\/32 stepping in HTSSOP-28. The A4988 from Allegro provides 2A\/35V with 1\/16 stepping for 3D printers. The TMC5130 from Trinamic offers 1\/256 stepping with StallGuard and CoolStep in QFN-48. For higher current, TB6600HG remains the best through-hole option at 4.5A.<\/p>"},"_links":{"self":[{"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/posts\/7870","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/comments?post=7870"}],"version-history":[{"count":1,"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/posts\/7870\/revisions"}],"predecessor-version":[{"id":8269,"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/posts\/7870\/revisions\/8269"}],"wp:attachment":[{"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/media?parent=7870"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/categories?post=7870"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/tags?post=7870"},{"taxonomy":"chip_brand","embeddable":true,"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/chip_brand?post=7870"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
