The TI E2E™ design support forums will undergo maintenance from July 11 to July 13. If you need design support during this time, open a new support request with our customer support center.
Part Number: LM27222 Good Day,
I am using an LM27222 as two half bridges in a full bridge amplifier scenario.
As of right now I'm trying to diagnose a single half bridge. I am using the sample circuit from the datasheet:
Where R1 is 1.5 OHM, C1…
Part Number: LM27222 Hello,
In the datasheet( https://www.ti.com/lit/ds/symlink/lm27222.pdf ) I can see that there is a 1500ohm resistor R1 in the Vcc+5V network to the VCC (pin 6). Could you please explain to me why this is there? Does this act as a current…
Part Number: LM27222 Hi Experts, May we ask for help? Our customer would just like to confirm if it is possible to leave the high side FET on for an indefinite amount of time or is there a time-limitation? Do he need to switch the low side FET on before…
Part Number: LM27222 The LM27222 LEN pin disables turn on of the low side FET. Is the high side FET drive still enabled and controlled by the PWM input? Operation is not explicitly stated in the data sheet.
Thanks, Mark
Part Number: LM27222 I want to use driver LM27222 for a bidirectional boost converter control. I am checking the Application Example in the datasheet and I see that the high-side and the low-side recommended MOSFETs are both N-channel but different in…
Part Number: LM27222 Hello, I'm having some troubles with the LM27222 while driving a dual active bridge Switching frequency: 250kHz Input Voltage: 20V Output Voltage: 20V Output current: up to 5A
(There are actually 4 LM27222 for driving the 8 switches…
Part Number: LM27222 Other Parts Discussed in Thread: UCC27282 Hi team,
What's the max duty cycle of LM27222? If the duty cycle is too large, there may be problems with the bootstrap circuit.
Best regards,
Nison
Part Number: LM27222 Other Parts Discussed in Thread: TINA-TI , , TPS28225 Tool/software: TINA-TI or Spice Models Please, I need a TINA-TI model of LM27222.

Part Number: LM27222 Other Parts Discussed in Thread: UCC27222 , TPS28225 , UCC27282 , UCC27212 Hi Team,
We are looking for High side driver but can’t find TI’s High side driver.
Therefore, we would like to use High side of LM27222(Half bridge…
Part Number: LM27222 I don't find any recommendation for the exposed pad connection for the QFN package variant. To which potential is the exposed pad connected inside the package? Can I connect it to GND?
