Part Number: UCD7232 Customer is attempting to operate UCD7232 at 500 kHz at a duty cycle > 97%. This results in an off time of < 3% * 2 us = 60 ns, but probably actually much less given slew rate and cross conduction timing.
The high side driver appears…
Part Number: UCD7232 Hi team,
Whether the UCD7232 can be used for driving the load at constant current? My requirement is to drive a Peltier element as load which consumes 4A maximum. Initially i want to drive the load at 3.4. 3.4 A maximum for a particular…
Other Parts Discussed in Thread: UCD7232 , UCD7231 Hello,
There appear to be very few, if any, differences between these 2 parts (UCD7232 and UCD7231). Could someone tell me what the difference is?
Thanks,
Brian
Other Parts Discussed in Thread: UCD9248 , UCD7232 Hi There,
I have a design using the UCD9248 and UCD7232.
There are many problems that I am seeing and cant pin down a hardware reason for the fault.
1: the UCD7232 regularly reports FLT. the output…
Hi Devith,
Go to Fusion Digital Power Designer -> Configure -> Phase/Rail Config, you can assign up to 8 phases to up to 4 rails.
UCD9248 is designed to work with smart power stage/driver such as UCD7242, UCD74120, UCD7232, etc., which have integrated…
UCD7232 might be a good start.
Also there are some FET integrated solutions that might be easier to use for you, such as UCD74106, UCD74111 and UCD74120.
UCD74120 cannot be paralleled in this way, because the MOSFETs are in different chips. UCD7242's two channels can be paralleled because the MOSFETs are in the same chip so they can automatically achieve current balance.
For high current rail you may…
UCD9224 would likely be the closest choice, it can provide up to 2 rails and up to 4 phases in various single and dual rail configurations.
The ZL6105 integrates the driver into the controller while the UCD9224 is just a controller and the driver is…
The USB adapter is detected.
100kohms were used for ADDR00&01 ; so the address will be 78 but no detection so far.
I am using 2.2kohm pullup resistor for PMBus signals.
12V is stepped down to 3.3 using the builtin regulator and used to power UCD9224…
