WSZT31007

The WSZT31007 is a high-precision, industrial strength, single-chip, Smart High-Voltage Switch designed by the National Semiconductor Corporation for use in power and measurement control applications. This device is intended for applications requiring high-voltage isolation with low electrical noise, and extremely low leakage, when connected to an external power source.

The WSZT31007 can be used in a range of power and measuring control applications. It can be used to control high voltage power lines, such as high voltage motor and transformer connections. It can also be used to switch voltage levels on a circuit board in order to measure or control power levels. Additionally, it can be used to control variable resistors, capacitors, and/or LED arrays.

The device is based on a buck converter architecture, featuring an advanced adaptive offset cancellation feature to decrease EMI noise. Using the device, power and measurement control applications\' accuracy and repeatability can be significantly improved. With the addition of a low-dropout (LDO) voltage regulator to the device, a digital electronic control system can provide hiccup-free fail-safe safety.

The WSZT31007 also provides high-voltage insulation up to 10000V. This is beneficial for applications that require signals over long distances and require protection from electrical noise or EMI. Furthermore, the device has a high level of integration and is built on an ASIC (Application Specific Integrated Circuit) which ensures that the device enclosure’s size is minimized.

The device operates by using pulse-width modulation (PWM) techniques. It modulates the width of the pulses applied to the switch based on the input signal and delivers these pulses to the isolated load. By varying the pulse width, the current passing through the switch can be regulated. Additionally, the device can be configured to convert AC line voltage to DC or DC to AC with the aid of an external switching device.

The power and measurement control applications enabled by WSZT31007 are also protected with a built-in protection mechanism. This protection feature prevents the device from being damaged due to over-voltage, under-voltage, and over-current conditions. Furthermore, a Smart High-Voltage Switch Protection feature helps protect against premature corrosion in industrial environments.

Overall, the WSZT31007 is a great device for applications requiring high-voltage isolation, low electrical noise, and reliable performance. From power and measuring control applications to converting AC-DC and DC-AC, the device offers a wide range of possibilities for industrial automation solutions.
