5.1.13 Battery Voltage Management
The TMC222 provides an internal battery voltage monitoring. The circuit goes into shutdown mode if
the battery voltage falls below threshold UV2, furthermore one threshold UV1 is implemented to
generate a low voltage warning.
Normal Voltage
<UV2> = '0'
<StepLoss> = '0'
Motion = enabled
Low Voltage
<UV2> = '0'
<StepLoss> = '0'
Motion = enabled
Stop Mode 2
<UV2> = '1'
<StepLoss> = '1'
HardStop
Motion = disabled
Stop Mode 1
<UV2> = '1'
<StepLoss> = '0'
Motion = disabled
