Description

The TB6560HQ is a PWM chopper-type sinusoidal micro-step bipolar stepping motor driver IC. It supports both 2-phase/1-2-phase/W1-2-phase/2W1-2-phase excitation mode and forward/reverse mode and is capable of low-vibration, high-performance drive of 2-phase bipolar type stepping motors using only a clock signal.

 

Features

• Single-chip bipolar sinusoidal micro-step stepping motor driver
• Uses high withstand voltage BiCD process : Ron (upper + lower) = 0.75 Ω (typ.)
• Forward and reverse rotation control available
• Selectable phase drive (2, 1-2, W1-2, and 2W1-2)
• High output withstand voltage: VCEO = 40 V
• High output current: IOUT = HQ: 3.5 A (peak) FG: A (peak)
• Packages: HZIP25-P-1.27/HQFP64-P-1010-0.50
• Built-in input pull-down resistor: 200 kΩ (typ.)
• Output monitor pin equipped: MO current (IMO (max) = 1 mA)
• Equipped with reset and enable pins
• Built-in overheat protection circuit

BP3125

Description

The IC is a high precision primary-side feedback and regulation controller for LED lighting, it operates in constant current control mode and is designed to work in inductor current discontinuous conduction mode and extremely suitable for flyback convertor under universal input, the output power of system should be less than 12W.

The Device integrates 600V power MOSFET . Since adopting primary sense and feedback control technology , the secondary sense and feedback circuit is eliminated. The loop compensation components are also removed while maintaining stability overall operating conditions. The low component counts and low BOM cost are realized.
