Other Parts Discussed in Thread: LM5101 Hi eveybody,
I'm trying to drive a BLDC motor and i made a driver for this. I used LM5101 for drive to mosfets. Initially driver worked but later LM5101 burned twice. I dont know why it burned. My pwm frequency…
Other Parts Discussed in Thread: LM5101A Hi,
I am currently doing a project on Regenerative Braking on E-Bike. To control the 24V DC Motor, I have choose the ""60-V, N-Channel NexFET™ Power MOSFETs"" and ""LM5101A/B/C 3A, 2A and 1A High Voltage High…
1. & 2. There are no specific average or peak current limits for these devices because in normal operation they only see very short current spikes. The main limitation is thermal issues being caused by losses in the diode and driver, however these are…
Other Parts Discussed in Thread: SM72295 , LM5101A I am strongly considering using the SM72295, I have a few technical questions first:
What is the maximum switching speed this part can support?
Is there any automatic protection against shoot…
Hello Johan,
I confirmed the typical Vf of the bootstrap diode with 5A forward current, and reviewed the expected maximum Vf at 5A current.
The typical Vf with 5A peak current is 1.65V. The estimated maximum Vf is 2.5V at 5A peak current.
The thermal…
Other Parts Discussed in Thread: UCC25800 Most applications including power delivery for industrial and automotive utilizing a half-bridge gate driver use the bootstrap diode and boot capacitor to generate the high side driver bias. This is the simplest…
Other Parts Discussed in Thread: UCC27201A Is there any reason LM5101AMX or UCC27201A should not be used in a non-isolated synchronous BOOST DC-DC converter? "Synchronous-boost converter" is not listed as one of the applications in either datasheet; I…
Part Number: UCC27301A
Tool/software:
Attached below is the .zip file for the PSpice project that contains a few different schematics that allow for testing the driver and its characteristics with respect to operating conditions set forth by the desired…
Hi,
I've attached the 2013 User's Guide for power products. Starting on page 53 you will find a selection of PWM controllers. many of these teh frequency can be varied according to external criteria.
As an example if you use a UC3842 it is a simple…
Gary,
Most any of our power controllers with dual output capability will provide the control. See attached document starting at page 50 with the dual output controllers on page 53 and 54 and choose what features you want.
Regards,
John
