Resolved! How can we increase soft start time for VIPER319XDTR?
Dear sir, We have followed STEVAL-VP319X1B development board schematic for converting 110V/230V AC to 5V DC. In one of board we found that inrush current limiting resistor is burn out. We have followed same part number for resistor which is in develo...
L99DZ200 & L99DZ80EP Load overcurrent problem
if L99DZ200 OUT9，13，14，15 & L99DZ80EP OUT1，6，7 will trigger overcurrent protection？
4 arms half-bridge symmetrical converter design
We want to control a 4 phase variable reluctance machine. For this we need to make (or buy) 4 arms half-bridge symmetrical converter with the following characteristics:Max current of the DC bus: 62 AMax DC bus voltage: 25.2 VMax PWM frequency: 30 kHz...
Strange description in datasheet of STPMIC1
In p. 28 of Datasheet - STPMIC1 - Highly integrated power management IC for micro processor units, 4.2.1, it says:3. Manually by setting VOUT[4:0] field of Table 38. BUCKx_MAIN_CR or Table 43. BUCKx_ALT_CR registers. Refer to Table 9. LDO output volt...
STNS01 specification
Hello, I am considering the STNS01 for a new project. The datasheet seems wrong. Is it possible to have power on SYS when starting with BAT, so with IN disconnected?How much is the maximum current flowing from IN to SYS?Thank you
Hello, I am using L6474 drive to drive the stepper motor and I am having issues as mentioned below.
Hello,I am using L6474 drive to drive the stepper motor and I am having issues as mentioned below.In status register the UVLO,TH_WRN,TH_SD and OCD flags are active low as mentioned in data sheet. In this the UVLO flag is set by undervoltage lockout o...
Resolved! L6474 only answers SPI command by sending the command back after 1 Byte delay
I'm controlling a L6474PD Stepper motor driver withan STM32F338 mcu. It is not a demo PCB but PCB made for our targeted product.I manage to control the motor with PWM and DIR pins, and send Disable and Enable SPI Commands that work ( basically all co...
