DollaTek THB6128 Stepper Motor Drive Control Module Two-phase Four-wire 30V 2A Drive Board

• Using THB6128 double full-bridge MOSFET driver, low on-resistance. Chip with automatic half-flow lock function, can reduce the lock motor heating. Chip built-in thermal protection, over-current protection.
• Maximum voltage 36V, peak current 2.2A, continuous current 2A.
• With 1,2,4,8,16,32,64,128 subdivided optional.
• Built-in 5V logic signal supply regulator chip, and add a current limiting resistor to reduce the high voltage input chip fever.
• Input reverse polarity protection.
