Part Number: UCC27201 Tool/software: Dear Expert
The attachment is the UCC27201A chip, which experiences delay changes under different loads. Please help analyze the cause. This problem only occurs in the upper tube driver, which outputs one of the two…
Part Number: UCC27201 Other Parts Discussed in Thread: UCC27200 , UCC27200A , Hi experts,
I'm a little confused about CMOS input and TTL thresholds. Can they be connected directly from C2000?
By the table, the input rising threshold is 5.8V, does it…
Part Number: UCC27201 Customer found some failure returns from field site after customer product released for some years. The failure part including MOSFET and boostrap cap.
In the schematic, DC57 and DC58 are 22uF Cap, and there is an ex. diode added…
Part Number: UCC27201 Hello,
We are using UCC27201 in one of our application, HO pin of UCC27201 remains ZERO W.R.T HS always, when HI is driven with high Signal also.
Attached the schematic below
As per device logic table. If HI pin - High & LI pin …
Hi Alexander,
Yeah, There is voltage on VBUS but it is 50 Volts so according to voltage divider it should be 25V on HS which is not the case.
i didn't understand second paragraph that how low side FET will bring HO to roughly match HS if HS is higher…
Part Number: UCC27201 我使用的是Ucc27201DR的物料,在实际批量使用过程在容易出现芯片供电引脚短路或MOS驱动短路的情况,以下是实际应用的电路,MOS管是IPB200N15N3 G ,工作频率是20KHz,上下死区1uS和4uS都测试过。 通过改驱动电阻和栅源极并电容优化过驱动波形进行测试还是会有一定的故障率,能帮忙分析一下可能存在的原因吗?
Part Number: UCC27201 Hello,
We are using UCC27201 in one of our application, HO pin of UCC27201 remains high always when LI is driven with high Signal also.
Attached the schematic below
PWMOUT1 is always high going to MOSFET, how to make it low when LI…
Part Number: UCC27201 Hi Support team
may I know why the ESD rating are different between UCC27201 & UCC27201-Q1
questions behind is due to shortage issue, my customer would like to use Q grade to instead of non-Q grade
But Q grade HBM rating is half…
