Diode, rectifier, and single are all types of electronic devices. UH2BHE3/5BT, which is a type of single device, is a three-terminal bidirectional dc switching performance Controller integrated circuit that provides protection functions such as over-current protection, over-temperature protection, and under-voltage protection. In terms of application, UH2BHE3/5BT is applicable to devices such as AC/DC, battery management system, devices protection and especially constant voltage/current applications, and in other applications, such as over/under-voltage protection energization, switch/charger control, LED driver, etc., UH2BHE3/5BT can provide the solutions to these applications.

UH2BHE3/5BT works by the principle that when the input voltage of UH2BHE3/5BT is greater than a reference voltage plus temperature compensation, the switch will turn off and a precise current limit is applied, and the output voltage follows the input voltage. The output of the control chip will drop 0.4V (typical) when the chip is turned on. The current limit value is between 0A~2.3A. A very precise 0.8A current limit value is set by a miniature shunt which is inside the product. The thermal compensation of the over current protection makes the over current protection more reliable and stable. Furthermore, the over-voltage protection is the same, which is the input voltage is greater than a given reference voltage plus temperature compensation, the switch will turn off and the output voltage will follow the input voltage. Over-temperature protection is also available to ensure that the chip temperature is over an adjustable predetermined temperature.

Besides these, UH2BHE3/5BT also provides several important features to benefit the applications. It can support a wide range of battery voltages from 19V~56V, and the high current capability of 2.3A will meet the actual needs. Also, the reverse efficient can reach up to 97.5%, which increases the power efficiency and output power. On the other hand, UH2BHE3/5BT is available both in SOP-8 package and DFLS8 package to save the system cost and make it easier to use. In a nutshell, UH2BHE3/5BT is an ideal switch device for the application such as AC/DC, Battery Management System, LED Driver and other Constant Voltage/Current applications.
