Resolved! LED1202 Address Pins
I notice that in the schematics for the STEVAL-LLL007M1 STEVAL-LLL007V1, part of the evaluation kit for the LED1202, several of the A0 pins for the attached LED1202s are pulled to ground with 10K resistors. However, in the datasheet for the LED1202 ...
Resolved! SPV1050 Temperature Range
Hi."Does STMicroelectronics have any plans to release the SPV1050 with an extended operating temperature range suitable for automotive (e.g., –40°C to +125°C) or military-grade applications?"Best Regards.
Revision code on STUSB4500
We have a batch of chips labelled M27400 and another marked M37400. Does this marking indicate the version number of the chips? I'm seeing a difference in behavior between them (the M34700 are reporting PE states I haven't seen previously). Thanks,
Resolved! STDES-2KW5CH48V
Hello,We are working on building 48V Lithium battery charger for AGV's. I would like to know if below Eval board from ST is available for purchase. STDES-2KW5CH48V2.5 kW - 48 V battery charger reference design for industrial light electric vehicles (...
Resolved! Clarification on Maximum Voltage Limitation of EVLSTGAP3S6S Board
I am planning to purchase the EVLSTGAP3S6S evaluation board for my research. While reviewing the datasheet, I noticed that the board is specified to support a high-voltage rail of up to 520 V, limited by the MOSFETs and capacitors. However, I observe...
Resolved! device recommendation for 208VAC, 480VAC, 40A AC heater switching application
Application : We are developing a AC switching circuit using dual MOSFET configuration. The application is for driving the 208VAC, 480VAC, 40A AC heaters to control its temperature.1. Is it preferred to use MOSFET or IGBT for this?2. Which MOSFET ser...
L7987L Not working as expected
Hello All,I am using L7987L to generate +15V from 24V. I have 10 same boards wherein I have used the same circuit (see below), I am able to generate 15V for 2 boards but in rest it is generating 1.22V only. R191 is 6.8kohm and diode D36 is US1M-E3/61...
Resolved! EVLVIPGAN50PD Modification for Standalone 12V Power Supply
Hi Sir, I would like to explore a specific use case that deviates from the standard design. My goal is to modify the EVLVIPGAN50PD to achieve a fixed 12V output, bypassing the USB PD negotiation functionality entirely. My intention is to utilize only...
Mastergan5 - Switching losses
Hi,I'm interested in the Mastergan5 IC.To evaluate it for our use case in a Class-D amplifier we need information about switching losses.These are commonly provided by suppliers of half bridge ICs by providing the Eon and Eoff values over switching v...
Resolved! STM6600 Implementation Queries
Hi,We are implementing STM6600 push button controller for our design and we have below queries. Is there any pull up connected to PS hold pin, can I connect this directly to 3.3V logic MCU.For variant STM6600DU25DM6F, tON blank is 11.2s, Do we need t...
