We have 6 drivers on one board controlled by MCU. Each driver has individual nSLEEP signal, but all DISABLE pins connected together and switched to the ground via nFET. I would like to control all nOL pins in the same way, i…
Part Number: DRV8873-Q1 Hi Team,
There is only one 8873 in the customer's design being used. To confirm proper SPI communication between the 8873 and the MCU, the customer would like to test it with the following method:
While the MCU side sends any…
Part Number: DRV8873-Q1 Other Parts Discussed in Thread: DRV8873S-Q1EVM We are using the H-bridge motor driver DRV8873S with part number DRV8873SPWPRQ1 and we're trying to use the outputs as independent half bridges which we do get to work on the development…
Part Number: DRV8873-Q1 Other Parts Discussed in Thread: DRV8873 , LM2902 Hi team,
A. The DRV8873 output is shorted to ground and goes into protection, but the output still has a residual voltage.
B. Output disconnected from ground, device recovered and…
Part Number: DRV8873-Q1 Other Parts Discussed in Thread: DRV8873 Hi team,
The test conditions are as follows:
supply power: 12V
Single current with a load: 1.5A
PWM drive frequency: 50KHz
The temperature rise will soon be around 100C. The temperature…
Part Number: DRV8873-Q1 Other Parts Discussed in Thread: DRV8873 Hello,
Customer is using 4 daisy-chained DRV8873SPWPRQ1. They have been using this part for a few years now without issue. They are working to update their Linux kernel, but running into…
Part Number: DRV8873-Q1
The schematic for hardware version (Figure 8) shows nOL pin internally pulled up to nSLEEP.
The description says: "the OLP test is performed at power-up or after exiting sleep mode if the nOL pin is NC or tied to GND", "OLA mode…
