DEI1028中文资料Voltage Clamping Circuit数据手册DEI规格书

描述 Description

The DEI 1028 is designed to provide the control for a power supply voltage clamp. It provides drive for a wide variety of P-Channel MOSFETS, linearly clamping the output. There is also a programmable Undervoltage Lockout feature that shuts the Power MOSFET off. Output voltage is maintained below the clamping threshold for Commercial-Off-The-Shelf switching supplies and op amps. If the clamping threshold is exceeded the out-put voltage is clamped at 35V maximum. The device is protected against a 100V spike of 100ms duration with over and undershoot protection

An open collector logic output is also provided that can be used as a power down interrupt for the system micro-processor.
