High current solenoid driver ic

 · TLESA. The TLE is a flexible, monolithic solenoid driver IC designed for the control of linear solenoids in automatic transmission, electronic stability control, and active suspension applications. The three channels can be used as either low-side or high-side drivers in any combination. The device includes the drive transistor Channels: A High-Performance Solenoid Driver In most applications, full current is only needed initially to pull in the solenoid driver. After the motion is complete, the current level in the solenoid can be lowered, which results in energy savings and much less heat generated in the coil. channel FET, or an IGBT, depending on the voltage and current of the solenoid. The pass transistor applies voltage to the solenoid and the series RC. The circuit turns on the solenoid in the exact same way as Figure 1. The difference is that when this solenoid turns off, the current in the solenoid is routed through two 1N diodes.

Four approaches to driving a current regulated solenoid are explored in simulations. The simulations had common control parts, for ease of comparison. The difference manifested in the power electronics driving the solenoid. The MOSFET driver logic relies on the current feedback being compared to its reference value. The TLESA is a flexible, monolithic solenoid driver IC designed for the control of linear solenoids in automatic transmission, electronic stability control, and active suspension applications. The three channels can be used as either lowside or highside drivers in any combination. The device includes the drive transistor. The instantaneous current that activates the solenoid actuator, called the peak current (IPEAK), can be high. However, once the relay or valve is closed, the current required to keep it in that condition, called the hold current (IHOLD), is significantly less than the peak current.

Many applications, particularly in computer peripherals, require a high power, fast solenoid driver circuit. In the past these circuits have been released. This solenoid can control a hydraulic pressure linearly in accordance with the control current. Torque. Sports-type high-speed engine. Continuous change. Ω(typ.) Common diode, Built in.
