Part Number: UCC21750-Q1 Other Parts Discussed in Thread: UCC21750 , ISO5452 Tool/software: dear \sir,
i am using ISO5852-Q and want replace to UCC21750-Q1 only difference AIN pin1 connect with COM and pin16 APWM connect with VEE (-8v supply ) can keep…
Part Number: ISO5852S-Q1 We are developing a 10kW integrated inverter for high speed (130k RPM) air blowers to provide process air for automotive fuel cell applications. Our blower is unique in that the rotating assembly is supported by gas foil bearings…
Hi Jieyu,
There seems to be a typo on the datasheet. The external clearance/creepage is 8mm instead of 14.5mm. The ISO5852S-Q1 datasheet provides the correct numbers. https://www.ti.com/lit/ds/symlink/iso5852s-q1.pdf
You can refer to picture below for…
Part Number: ISO5852S-Q1 Hi,
We are designing gate driver for IGBT(IKW40N120CS6) which short circuit handling time is very low (3us), for such short time DESAT protection if we calculate blanking capacitor using current source of 0.5mA, it will come around…
Part Number: ISO5852S-Q1 Other Parts Discussed in Thread: ISO5852S Hi,
I have some doubts related to the desat protection and associated soft turn off feature in the ISO5852S gate driver.
1. Generally when someone design a gate driver using ISO5852 with…
Part Number: ISO5852S-Q1 We completely removed the DESAT blanking capacitor, but the voltage on the DESAT pin is still ramping and takes about 7uSec to reach 7V. We also removed the Schottky diode that's was in parallel with the Capacitor but it did not…
Part Number: ISO5852S-Q1 Hi Team,
I am working with ISO5852S-Q1 for Drive Development.
From DSP through Buffer IC the PWM are transferred to the gate driver.
I have these observations
1) If am connecting my laptop charger and JTAG together with low…

Hello,
We're designing Automotive motor drive with UDC MAX = 880V. Regarding standard we need creepage min. 10mm. All your reinforced isolated…
Part Number: ISO5852S-Q1 Other Parts Discussed in Thread: UCC21750 Hello,
The problem we are facing is that we cannot see the soft turn-off from the output pin after the Desat protection is triggered. The output of the chip turns to VEE2 only within around…
Part Number: ISO5852S-Q1 Hi,
Is it possible to use bootstrap power supply for ISO5852S-Q1 ?? So that I shall require only three power supply for an inverter operation ??
Any specific disadvantages with the same??
Regards
