Part Number: TPS3806 Other Parts Discussed in Thread: TPS3808 , TPS3899 Dear team
At present, the customer has some questions about the Datasheet page 6. (1) Is there a definition of TEST CONDITIONS in the blue box? (2) Is there a value for the minimum…
Part Number: TPS3806 How can I slow down the detection time with TPS3806J20DBVR? Is it possible to slow down by adding a capacitor between the LSENSE pin and GND?
Part Number: TPS3806 Hi team,
The customer needs to get the differences between TPS3806J20 and TPS3806I33.
The datasheet shows VDD is from 1.3V to 6V. But the datasheet also shows J20 version can only
support 1.8V VDD and I33 version can support…
Hi Mike,
You the Electrical Characteristics table provides the threshold voltages at the VDD and LSENSE pins of the device.
For LSENSE you can use equation 1 on page 5 of the datasheet to calculate the threshold at top of the resistor divider…
Other Parts Discussed in Thread: TPS3306 TPS3306 -33 c an be powered by 3.3V on VDD and sense 5V on SENSE1 ?
The maximum voltage for SENSE input is (VDD+0.3)VIT/1.25V (VIT = 4,55V for SENSE1)
Here the schematic, 2 circuits (for a total of 10) have…
Part Number: TPS3806I33-Q1 Other Parts Discussed in Thread: TPS3806 Hi
we would like to use TPS3806 for voltage monitor application , and design width Hysteresis range avoid power transition to cause unexpected behavior of Reset pin
but divider resistance…
Hello Yusong,
Yes, RSTSENSE output of TPS3806 can be used to turnoff of TPS2663x by shutdown pin to supply the load from main source.
Is there any hysteresis specification on power from 2nd Source?
Eli,
The thresholds of INA+ and INB- can be configured using a resistor divider as shown below:
This device allows for undervoltage and overvoltage monitoring and the resistor value calculation is shown in section 8.2.2.1 of the datasheet. …
Hi Morteza,
For such a wide hysteresis, you could look at the TPS3806, which has dual voltage detectors and with adjustable hysteresis. The lower threshold (LSENSE) and higher threshold (HSENSE) can both be set using resistor dividers – you will need…
