Part Number: DRV110 The overexcitation voltage of the brake is 24V and the current is 0.83A. The steady-state excitation voltage is 7V and the current is 0.3A. The bus voltage is currently 48V. The current plan is to use a half-bridge + LC filtering drive…
Part Number: DRV110 Hello,
We have used the DRV110 as relay driver in past developments, the IC works as intended. However, we have changed the relay with a new one and the circuit is presenting a much lower frequency than the one prescrived throught…
Part Number: DRV110 I'm driving a brake module which acts much like a solenoid... The circuit operates from 24VDC to 80VDC but the DRV110 Vin is provided by a 15V regulator... The circuits works as expected until the voltage is between 57V and 80V...…
Part Number: DRV110 Hello, my selenoid makes an audible noise, and it is impossible to completely remove it.
In datasheet there is maximal PWM frequency 25 kHz by 160kOhm resistor.
But it looks that DRV 110 can physically work much higher. What is…
Part Number: DRV110 hello,
I need to drive solenoid which needs 1.5A and after that 0.6A to hold.
Or 24V and drop to 12V to hold.
Is it possible to use DRV110?
how to choose the resistors Rpeak and Rhold to have 1.5A and 0.6A
Part Number: DRV110 Other Parts Discussed in Thread: DAC80502 I want to make both the hold and peak currents adjustable via a DAC (see below). For this, we are using the DAC80502 with a 1.25V output range. Above 1V, the current I_RDAC can become negative…
Part Number: DRV110 Hello, I get some samples and test DRV110 selenoid driver. I set rougly 1Amp peak current, 250mAmps hold current, peak time 200ms. It works well from 9 to 14 volts, but however I use higher voltage, PWM has huge inaccuracy.
see oscilograms…
Part Number: DRV110 Other Parts Discussed in Thread: AMC1300 Hello,
I've have been doing some testing using the DRV110.
The solenoid it self is being energized off of the 270VDC Bus.
Characteristics of the soleniod are 18.9mH and 13.95DCR.
We…
Part Number: DRV110 Tool/software: Hello, I'm trying to simulate the DRV110 in LTspice but seems that there is something wrong in the model, in pratical the regulation of the PWM is not like is aspected to be, here the test circuit:
.
We can see that…
Part Number: DRV110 Hi, I use the DRV110 to drive a 24V power relay. Schematic is as follows.
Now I can see that the voltage at VIN is ramping up and down. This is also seen on the current in the power relay:
Channel C1 (yellow) shows the ripple…
