Part Number: DRV8842 Hi team, I would like to get your input with the customer inquiry below: In the customer design, With Rsense=100 mohms, , he has a max of 1.2A chopping current with the driver OUT1/2 (voltages) being chopped when supplied with a VM…
Part Number: DRV8842 Other Parts Discussed in Thread: DRV8844
Hi Team,
Good day! I am posting this on behalf of the customer. I want to use the DRV8842 to drive a small AC induction motor.
I envision using 2 PWM channels an MSP430, 1 on IN1, and…
Part Number: DRV8842 Hi, I'm using the DRV8842PWP to control a motor that only needs up to 3A, but the inrush can go up to 18A.
When I use the bench power supply (up to 3A) the motor works fine, but when I try with the embedded PSU (up to 20A) it triggers…
Part Number: DRV8842 Other Parts Discussed in Thread: DRV8872 , Hi folks,
I have an in-house designed and built control board used to control some of our test equipment, it has 2 relays configured as a H bridge. These relays have been wearing out…
Part Number: DRV8842 Hello ,
I'm using the DRV8842. In the "Typical Application part given in the datasheet, there is a equation for calculating I_Trip depending on VREF and R_Sense. Is I_Trip = 1.5A by one directional current or is the bidirectional…
Part Number: DRV8842 Hi Experts,
Good day.
We would like to know what's the input capacitance (IN1 and IN2) for this orderable part: DRV8842PWPR? We're trying to find it from D/S but there is no information about it.
Thank you.
Regards, Archie…
Part Number: DRV8842 Hi Team,
The customer recently used the H-bridge to drive DRV8842, the schematic diagram is as follows:
After using DC12V power supply, FPGA is used to generate low-frequency PWM with amplitude of 3.3V.
There is a glitch…
Part Number: DRV8842 I have a design based on the DRV8842 that drives a linear motor (a mechanical arm, like a solenoid, with a coil 1.2 mH, 5 Ohms). The mechanical arm have magnets that keep it stable at the two stops like a latch solenoid. In order…
Part Number: DRV8842 Other Parts Discussed in Thread: TPS54429 , Hi there,
I've got 2x DRV8842's on my board which is powered from a 24V PSU. The IO lines IN1, IN2, I0, DECAY, nRESET, nSLEEP and nFAULT are connected to a 3.3V MCU. The IN1 and IN2 are…
Part Number: DRV8842 Other Parts Discussed in Thread: DRV8704 HI All,
Am having an issue with the HBRIDGE DRV8842 and the behavior is different in EVM and in my board.
The schematic is pretty much the same.
I have document my observation in the…
