Part Number: DRV8210EVM Other Parts Discussed in Thread: DRV8212EVM , DRV8220EVM , Version A and E1 of the DRV8210EVM, DRV8212EVM, and DRV8220EVM have a silkscreen error where the "IN1/EN" and the "IN2/PH" silkscreen label placement is incorrect. The correct…
Part Number: DRV8244-Q1 Other Parts Discussed in Thread: DRV8245S-Q1LEVM
The SPI (S) and SPI (P) versions of these chips are very similar - same specs, both SPI controlled. However, the key difference is that the (P) version uses an external 5V for the…
Part Number: DRV8245S-Q1LEVM
Our team recently discovered an issue with the recently released DRV8245S-Q1LEVM. The EVM fails to connect to the GUI, and the nFAULT LED doesn't display the status of the nFAULT signal on the microcontroller. This is…

As DRV8432 moves into the end of its life the next step is to choose an alternative part. This device had a broad application base in medical devices, portable electronics…
Welcome to a new FAQ series, Tackling BLDC Datasheets. A datasheet is the most comprehensive and accessible literature publicly available. Texas Instruments provides comprehensive datasheets presenting enormous amounts of information and data about an…
Other Parts Discussed in Thread: MSP-EXP430FR2355 , MCF8316A , MCF8316AEVM , MCF8315A , MCT8329A , MCT8315A , MCT8316A The MCx8xx family of integrated motor drivers contains registers and on-board EEPROM that can be interfaced and programmed using an external…
The reason that SHx floats is due to the high-side gate architecture. When the low-side FET is not on, the leakage from SHx will have no path to ground which means that SHx will float up to VM, through the body diode of the FET, as shown in the diagram…
Other Parts Discussed in Thread: DRV8910-Q1 , DRV8904-Q1 , DRV8906-Q1 , DRV8908-Q1 , DRV8912-Q1 DRV89xx-Q1 (DRV8904-Q1,DRV8906-Q1,DRV8908-Q1, DRV8910-Q1, DRV8912-Q1) device has internal PWM generator. When PWM Duty is set as FFh(max), it is very close to 100…
Other Parts Discussed in Thread: DRV8329 , DRV832X When determining the MOSFETs a gate driver can support one of the specifications that should be looked at is the maximum average gate current that the gate driver can supply. To switch a MOSFET gate drivers…
