Part Number: TPS2491 Hello, TI expert
I have a TPS2491 design. it works only a few times, then the MosFET will be damaged. became a pass through. ( always on). Vraw is a 19V AD/DC adaptor, FDS86140 has +/-20V Vgs. I can add a 15V Zener diode between…
Part Number: TPS2491 Hi,TI
We plan to use the TPS2491 to control the battery output and provide hot-swap protection. To distribute the stress across multiple devices, we intend to connect four DFN 5 mm × 6 mm MOSFETs in parallel.
Could you please…
Part Number: TPS2491 Other Parts Discussed in Thread: LM5069 , Hi Team,
We plan to use a bulk capacitor of approximately 20,000 µF. Based on the reference design, only one MOSFET is used between VOUT and VIN. We tested the EVK with a 20,000 µF bulk…

Hi, I have some problems with disabling TPS2491 externally. As one can see the picture below, CURR_LIM_SHDN is an external signal this is set by a microcontroller. The CURR_LIM_SHDN makes sure that optocoupler pulls the CURR_LIM_EN…
Part Number: TPS2491 Other Parts Discussed in Thread: LM5137 , , LM5069 , TPS1685 Hey, dear TI engineer, how are you?
Recently, I've been working on a power board design. The specification of the board is:
Input voltage( wide) = 18V-60VDC ( from batteries…
Part Number: TPS2491 Tool/software: Hello
The Enable pin of the TPS2491 is used to control the ON/OFF of 24V DC to the load.
The maximum current of the load is 66A.
I use three MOSFETs, 80V, 310A, 1.6mΩ, in parallel.
The problem is that when Enable…
Part Number: TPS2491 Tool/software: Dear E2E support menber.
About TPS2491DGSR.
We can confirm the temperature characteristics of VSENSE (50mV typ) from the graph shown below.
Please provide similar graphs for VCL (25mV typ) and VREF (4V typ). …
Part Number: TPS2491 Hi ,
TPS2491 is used part of the design ,with the Input [VCC} being 12V.
I have tried measuring the Gate output voltage and i could see that the voltage measured is around 25V .
As per the Datasheet , the max Gate output voltage…
Part Number: TPS2491 Other Parts Discussed in Thread: BQ24610 , , LM74930 Dear TI experts,
My customer have a problem with operating battery applied application.
They see inrush current when they attach battry to system, so FET is sometimes dead…
Part Number: TPS2491 Other Parts Discussed in Thread: TPS1663 Tool/software: I'm looking for a hot-swap controller or something similar to soft-start an inverter. Supply = 48V 1000AH battery. Capacitance to charge is about 100,000uF. The main feature…
