The L6228Q is a fully integrated DMOS stepper motor driver with non-dissipative overcurrent protection, implemented using BCDmultipower technology, which combines isolated DMOS power transistors with CMOS and bipolar circuits on the same chip. The device includes all the circuits required to drive a two-phase bipolar stepper motor, including: dual DMOS full bridge, a constant turn-off …
The L6562 is a current mode PFC controller operating in transition mode (TM). Pin to pin compatible with the predecessor L6561, which offers better performance. All functions 1% (@tJ =25˚C) internal reference voltage To disable the feature DIP - 8 / SO - 8 packaging ECOPACK ® -600/+800mA totem grid driver with UVLO pull-down and …
L6382D5 is suitable for embedded PFC and half-bridge microcontrolled electronic ballasts. The L6382D5 includes four MOSFET driver stages (for PFC, half-bridge, and preheated MOSFET) and a power management unit (PMU), which also has a reference that can power the microcontroller in any situation. In addition to improving application efficiency, the L6382D5 also reduces material costs …
Nowadays, IC is "active" in people's sight with faster speed, smaller volume and larger capacity. Its complexity is far beyond people's imagination. So, is it difficult to develop IC? What is the flow of IC development? What is IC development? "IC development is also called" IC design, is how to design and develop integrated circuits, …
TPS54231DR Switching regulator integrates low Ros (on) high sideMOSFET asynchronous Buck converter. To improve efficiency under light load, the function of pulse skipping Eco mode is automatically activated. In addition, the 1MA down power current allows the device to be used in battery-powered applications. TPS54231DR current mode control with internal slope compensation simplifies external compensation …
Troubleshooting logic of motor abnormal heating: 1. Check whether the motor generation setting is correct. 2. Check whether the motor is learning parameters. 3. Whether the frequency converter always runs at low speed, 4. Whether the motor is a inverter motor, 5. Whether the load is too large, 6. Is the three-phase motor balanced? 7. …
