JAJSL26B January 2021 – April 2022 DRV8316
PRODUCTION DATA
The DRV8316 family of devices provides four different control modes to support various commutation and control methods. Table 8-2 shows the various modes of the DRV8316 device.
MODE Type | MODE Pin (Hardware Variant) | PWM_MODE Bits (SPI Variant) | MODE | VREF/ILIM pin configuration | CSA output (SOx) |
---|---|---|---|---|---|
Mode 1 | Connected to AGND | PWM_MODE = 00b | 6x Mode | VREF: Reference for CSA | SOx available |
Mode 2 | Hi-Z | PWM_MODE = 01b | 6x Mode with Current Limit | ILIM: Threshold for cycle by cycle current limit | SOx not available |
Mode 3 | Connected to AVDD with RMODE | PWM_MODE = 10b | 3x Mode | VREF: Reference for CSA | SOx available |
Mode 4 | Connected to AVDD | PWM_MODE = 11b | 3x Mode with Current Limit | ILIM: Threshold for cycle by cycle current limit | SOx not available |
Texas Instruments does not recommend changing the MODE pin or PWM_MODE register during operation of the power MOSFETs. Set all INHx and INLx pins to logic low before changing the MODE pin or PWM_MODE register.
