TB9053FTG,TB9054FTG Motor drive output Is EN/ENB pulse input Function EN1 ENB1 EN2 ENB2 DIAG1 DIAG2 needed when DIAG pin pin OUT1 OUT2 OUT3 OUT4 is cleared? When initial/restarted diagnosis detects an error (Detection of VBAT/VCC under-voltage or over- X X X X No L L *1 *1 *1 *1 temperature) When Initial/restarted diagnosis detects an error (Detection of Ch1- Ch2 over-current or open load X X X X No L L *1 *1 *1 *1 during operation/non-operation) When initial/restarted diagnosis is attempted but it does not start (Detection of VBAT/VCC under- X X X X No L L Hiz Hiz Hiz Hiz voltage or over-temperature) When initial/restarted diagnosis is attempted but it does not start (Detection of Ch1-Ch2 over-current X X X X No L L Hiz Hiz Hiz Hiz or open load during operation/non- operation) When SPI communication disruption is detected X X X X No L L *2 *2 *2 *2 When an SPI communication CRC error is detected X X X X No L L H/L/Hiz H/L/Hiz H/L/Hiz H/L/Hiz When a fault SPI communication SCLK clock count is detected X X X X No L L H/L/Hiz H/L/Hiz H/L/Hiz H/L/Hiz When a fault SPI communication address is detected X X X X No L L H/L/Hiz H/L/Hiz H/L/Hiz H/L/Hiz *1: Operation similar to Table 5.2 H-bridge motor function 2 *2: Operation specified in CONFIG1 DATA[8 ] Note: In combined 2-channel mode, externally short-circuit ISEL1/2, EN1/2, ENB1/2, OUT1/2, and OUT3/4. However, EN2/ENB2 are effective as analog signals to control the output DMOS gates but ineffective as signals supplied to the logic circuit. © 20 20 9 2020-12-10 Toshiba Electronic Devices & Storage Corporation
