STNS01 occasionally getting hot while charging
Posted on June 01, 2016 at 13:15Hi to all, i implemented the STNS01 on a small wireless sensor. The STNS01 is charging a coin cell type LIR2440. The schematics for the battery charging part of the sensor are attached below. Usually the charging proc...
L297 stepper driver help
Posted on April 20, 2017 at 00:26Hi AllI need to put L297 stepper driver in 'wave drive mode' permanently. I connect HALf/FULL pin 19 to GND but it work in 'NORMAL DRIVE MODE' by default.I tried to connect pin 19 to low in even state and get the 'wa...
Relation of L6470H Speed Related Parameters
Posted on April 07, 2017 at 08:13Hi, I am using L6470H with stm32f103 for past few months in our project. I have clarified the KVAL value relation with motor through online.I worked out all the commands for motor running given in the datasheet...
I am usind LD1085 voltage regulator connected to a 500mA of load. When the capacitor connected is 100uF at both i/p and o/p it is becoming too hot with 30-50 sec. Same is the condition with 10uFcapacitor at i/p and o/p and also with 22uF at i/p and 47uFa
