Part Number: TPS2640 Hi,
When user sets "Current limit with LATCHOFF mode", datasheet requires 402-kohm resistor between MODE pin and RTN pin. Does TPS2640 need exact 402k-ohm resistor? How about 420k-ohm resistor? Please let us know the range of resistor…
Part Number: TPS2640 Good day all.
I have a plan to use TPS2640 for new circuit.
In that circuit, I want to connect SHDN pin to power supply line directly.
Because new circuit requires very high noise immunity performance.
Based on another thread…
Part Number: TPS2640 Hello,
I wish to know what is the internal voltage value put on the internal pull-up on the SHDN_NOT pin (pin 7 on the HTSSOP package of the eFuse TPS26400PWPR). The only information available from the datasheet is the Avdd. But…
Part Number: TPS2640 Other Parts Discussed in Thread: TPS2660 Hi, regarding supression of transients: Figure 10.1 and Figure 11-1 in datasheet describes a TVS diode in parallell to the efuse (D2) - between Vin and Vout. This diode is not described for…
Part Number: TPS2640 Hello team,
Layout of the data sheet has Through-Hole on b ottom layer . On the other hand, EVM layout does not have it.
Which is the recommended layout in the view point of thermal performance?
What is the difference of the…
Part Number: TPS2640 Hi team,
I’ got questions on the equations on the datasheet, specifically equation 17 and 21 (below).
↓ Equation 17
↓ Equation 21
I'm guessing there were typo and those should be:
Equation 17: PD(startup)=PD(inrush…
Part Number: TPS2640 Hi team,
I have required 28V 2A EFuse with a quick discharge. Is this possible via the 'dVdt' pin of TPS2640? Suggest if there is any other solution.
Thanks, regards

Part Number: TPS2640 Hi team,
Could you give me comment on following customer question?
Q. Why is there difference between I(CB) in the electrical characteristic table and derived result of the eq. (4)?
When using R=120k, R=5.36k with the eq. (4…
