Part Number: INA186 Other Parts Discussed in Thread: INA230 , INA169 Tool/software: Hello TI Team,
We are planning to use INA186 amplifier for current measurement of -24VDC@1A supply.
As per the attached datasheet reference image, INA186 is used for the…
Hi,
That may cause device damage if load side short circuit occurs. Because the OC limit of the device is over 3A, when output short, the inductor will saturate so the inductance is much smaller than rated value. The inductor current slew rate will be…
The maximum current will be used between 1A and 1.5A. The DCDC I inquired about will be used as a power source for the opamp, so I would appreciate it if you could also introduce the negative power DCDC to be used together.
Part Number: TPS61094 Tool/software: Hello,
I have some questions during validation TPS61094 via TPS61094 EVB.
Test conditions:
Vin = 5.2V (makes sure Vin > target Vout+0.1V)
Vout = 5V
Charge current = 300mA
Charge voltage = 5.1V
Load current = 1A…
Hi Yamamoto-san,
Shunsuke Yamamoto said: May I know how to calculate the output current on IPROPI pin when high side current is 1A?
In the DRV824x-Q1 current sensing is done on HSFETs only. So IRPOPI always has the scaled down representation of the high…
Hi Ivy,
So it looks like no shoot through is happening, it is important to look at GHx to SHx when trying to view something like deadtime. I think those spikes might be present because the customer is using 1A for IDRIVE. 1A might be too much for the…
Hi Kaan,
Yes, 7mA is too small to enter into PWM mode.
So do you mean that the output voltage is much lower than 5.1V when battery voltage is ~3.3V and the load current is ~1A?
It should not be the expected behavior of TPS61235P, could you please double…
Part Number: DRV8350 Tool/software: Dear Ti team
First, we're using "DRV8350R" part.
I have a question about this part.
IDRIVE Setting.
As you can see 9.2.1.2.2 IDRIVE Configuration in datasheet
we can calculate IDRIVEP, IDRIVEN values…
Hi Himanshu,
The lowest noise LDO on the market is the TPS7A94 (1A output capable) which also has very high PSRR and fast transient response. This is the clear choice for an LDO to use given your requirements (ultra low noise, high PSRR, fast transient…
Hello,
Thank you for your thermal question.
Here is the equation:
(8V-5V) x 1A = 3W, (3W x 32.5 degC/W) + 40 C = 137.5 C, where 32.5 degC/W is the thetaJA datasheet value.
This device goes into thermal shutdown at 170 deg C, so there should not be a concern…
