conduction at a time, so the conduction loss is small, high efficiency. The output can either sink current to the load or pump current from the load. The push-pull output stage increases the load capacity of the circuit and increases the switching speed.Second, open-drain output: The output is equivalent to the transistor collector, to get a high-level state requires a pull-up resistor. Suitable for the current-type drive, its ability to absorb current is relatively strong (generally 20mA or le

This time in the processing of the board problem has made several mistakes. 1, although VCC and GND are short, the first reaction is to recall what operation caused the accident, in order to determine where the problem. 2, although the problem is located in the chip by electrostatic breakdown, but the removable chip did not go to confirm the error, (which caused a series of subsequent problems) 3. After the change of the film, found

relatively strong (generally 20mA or less). The circuit of the open-drain form has several features: 1, the use of external circuit drive capability, reduce the internal drive IC. When the IC internal MOSFET is on, the drive current flows from the external VCC through the pull-up resistor, MOSFET to GND. Only a small gate drive current is required inside the IC.2, generally, the open-drain is used to connect different levels of the device, matching t

Based on the contact Coordinate Position and corresponding coordinate position, the microcontroller can know the intention of the touch. 3 TSC2046 operating mode and control wordThe TSC2046 mode can be set to 8-bit or 12-bit working mode. The input mode is differential input and single-ended input. This article describes the 12-bit differential input mode

MOS of the IC are turned on, the driving current is from the external VCC flowing through the R pull-up, the MOs to Gnd. The IC only needs a very low gate drive current. 1.2. You can connect multiple pin pairs with open/missing output to an online line. Form a "logical" relationship. 1. When any one of pin_a, pin_ B, and pin_c gets low, the logic for online exposure is 0. This is also the principle that I2C, SMBus, and other bus determine the bus occ
