Part Number: LMH6882 Other Parts Discussed in Thread: TLV431 Tool/software: For AC coupled application, what happens if the OCM pin is terminated by a resistor connected to ground? Basically, the OCM pin is not biased. Will the LMH6882 still function…
Part Number: TLV431 Other Parts Discussed in Thread: TINA-TI , Tool/software: TINA-TI or Spice Models Hi team,
My customer is working with an IC ‘TLV431’ in one of our designs and was trying to simulate it on LTspice.
We created a symbol…
Part Number: UCC25640EVM-020 Other Parts Discussed in Thread: UCC256404 , UCC256402 , TLV431 Tool/software: Hi TI team
In UCC25640EVM-020 VO618A optocoupler is used.
As per the design the opto LED current is (12V-1.2V)/9.09Kohm = 1.18mA. The CTR of VO618A…
Part Number: TLV431 Hi Support team
My customer want to add a cap across the resistor from gate to cathode. there is another resistor from gate to anode. The question is, with this cap, when the circuit is discharged, he is seeing current injected into…
Part Number: TLVH431 Other Parts Discussed in Thread: TINA-TI , TLV431 , , LMV431 Tool/software: TINA-TI or Spice Models Hi,
several weeks ago in February I reported some problems with the SPICE models of the shunt regulators TLVH431, TLV431 and LMV431. …
Part Number: TLV431 Other Parts Discussed in Thread: TL431 Hi all,
I'm doing a theoretical voltage accuracy analysis on TLV431 Low-Voltage Adjustable Precision Shunt Regulator with Vka > Vref and I found some specifications in the datasheet, which don…
Part Number: TLV431 Other Parts Discussed in Thread: TLVH431 We use the TLV431 in the undervoltage scheme as advised on an application note. The only difference is our 0V is connected to earth.
We are having products returned from customers for failing…
Part Number: TLV431 Other Parts Discussed in Thread: LMV431 , , TINA-TI I need a circuit to limit the voltage excursion in an A/D input. The A/D alowed input voltage range goes from -0.1V to 1.9V. Below a draft of the circuit I am thinking of to solve this…
Part Number: UCC28C42 Other Parts Discussed in Thread: TL431 , TLV431 , UC3844 Tool/software:
Hi team,
When customer want to use UCC28C42 in the new circuit design. Vin=19.2VDC. There are total 3 outputs. Vout1=5V 0.7A(main feedback winding). Vout2=…
Hi Ben,
Yes, that's a valid use case, but it will take a slightly more creative solution. One more question, will IN1 be dropped to a lower voltage during operation, or will it just be connected/disconnected?
What do you think about something like…
