SLLSFH8A August 2021 – December 2021 MCT8316A
Low-side braking mode is configured by setting MTR_STOP to 010b. When a motor stop command is received, the output speed is reduced to a value defined by ACT_SPIN_BRK_THR prior to turning all low-side MOSFETs ON (see example Figure 8-43) for a time configured by MTR_STOP_BRK_TIME. If the motor speed is below ACT_SPIN_BRK_THR prior to receiving stop command, then the MCT8316A transitions directly into the brake state. After applying the brake for MTR_STOP_BRK_TIME, the MCT8316A transitions into the Hi-Z state by turning OFF all MOSFETs.
The MCT8316A can also enter low-side braking through BRAKE pin input. When BRAKE pin is pulled to HIGH state, the output speed is reduced to a value defined by BRAKE_DUTY_THRESHOLD prior to turning all low-side MOSFETs ON. In this case, MCT8316A stays in low-side brake state till BRAKE pin changes to LOW state.
