Diodes' precision adjustable current limiting power switch

     Diodes introduced AP22653Q programmable current limiting power switch. This car specification device simplifies the design of the power system while ensuring durability and providing a controlled and protected power path. Its rated continuous load current is up to 1.5A. The main products are used to protect the USB port and ECU power rail of the vehicle, as well as the information entertainment and remote communication subsystem.

     The strict accuracy margin of AP22653Q at high current level is ± 7%. With the use of standard external resistors, the current limit threshold can be easily set at any point between 125mA and 1735mA. The controlled rise and fall time of this device helps to mitigate the surge effect during the opening/closing period. In addition, its 5 μ S Short circuit response helps avoid situations where system shutdown/restart is required.

    The on resistance of AP22653Q is 55m Ω (typical value), which greatly reduces the power loss and voltage drop under high load current. The reverse current protection integrated in this device can avoid reverse current when external power is supplied to peripheral devices. In addition, there are overheat protection and undervoltage locking functions. The operating temperature range of - 40 ° C to 125 ° C is supported.

     AP22653Q power switch complies with AEC-Q100 Grade 1 specification and can be manufactured in IATF 16949 certified production facilities and passed PPAP. The product is packaged in a compact SOT26 package.
