Part Number: DRV8421
I am using the DRV8421ADFUR to drive two motors for an RC Car. The motor driver input pins IN1-IN4 are driven by an Arduino Nano (3.3V logic). The output pins OUT1 and OUT2 are connected to a brushed DC motor and OUT3 and OUT4 are…
Part Number: DRV8421 Other Parts Discussed in Thread: DRV8411A Hello team,
My customer would like to add current sense point for Low-Power Circuit defined (by IEC60335-1 and UL 6073). But when resistor is added to DRV8421A GND, the level of control…
Part Number: DRV8421 Other Parts Discussed in Thread: DRV8847 Hi team,
Our customer is currently using the TC78H611FNG(O_EL), and we have received a request to evaluate TI devices as potential alternatives for cost reduction purposes.
From a cost…
Part Number: DRV8421 Hello team,
Can you tell me an advice on VIL / VIH error across all temperature range from min/max value?
The datasheet spec is defined under TA=25°C.
<Datasheet>
TA = 25°C, over recommended operating conditions unless otherwise…
Part Number: DRV8421 Other Parts Discussed in Thread: ULN2003A Hello team,
Can you prepare a graph for "Maximum Collector Current vs Duty Cycle" like ULN2003A?
My customer is considering to apply DRV8421A instead of transistor array like ULN2003A…
Part Number: DRV8421 Hello team,
Can you tell me what is a basic protection circuit against surge voltage from solenoid load?
I could not find an example in the datasheet. The use case of VM is up to 15V, but over voltage (>18V) might be input by…
Part Number: TPS65400 Other Parts Discussed in Thread: DRV8421 , TMS320F28P550SJ Tool/software:
We want to connect SW1 to DRV8421 to driver a 12V, 0.4A stepper motor, will a 10uH output inductor be a proper choice? To confirm the compensation configuration…
Part Number: DRV8421BEVM Other Parts Discussed in Thread: DRV8421 Tool/software: hi team,
customer aim to use DRV8421B to drive 2 BDC motor. but the 2 motor have different gear, so there would be one motor stop and another still running use case.
