PRODUCTION DATA
If the die temperature exceeds the thermal shutdown limit (TOTSD), all MOSFETs are disabled, and the nFAULT pins are driven low. The charge pump is disabled during this condition. The thermal shutdown protection can operate in two different modes: latched shutdown and automatic retry.
The ENABLE1 pin should be Hi-Z to select latched shutdown mode, and should be HIGH (>2.7V) to select automatic retry mode. ENABLE1 pin controls the OTSD recovery method for both Stepper drivers.
