CH213 Datasheet https://wch-ic.com 5V*0.5A low voltage drop diode chip CH213 Datasheet Version: V1.1 https://wch-ic.com 1. Overview CH213 is a low dropout ideal diode chip with current limiting function. The chip has integrated modules for overcurrent protection, short-circuit protection, over-temperature protection, power supply polarity protection, etc. It supports DC applications with no more than 1A current at 5V, and can protect the power supply system by limiting the output current when an over-current condition such as a short-circuit occurs at the VO output, and can protect the load circuit at the VO output when the input power supply polarity is wrong. The CH213 is equivalent to a Schottky Barrier Diode plus a self-recovery fuse, but with a substantially lower onvoltage drop and more rapid over-current protection. The following is the internal block diagram of CH213 for reference only. VIN(+) Anode GND Current Sense Thermal Sense Driver Comparator VOUT(-) Cathode Current Limit Detect 2. Feature          V1.1 Built-in power switching tube, typical 160mΩ on-resistance. Low turn-on voltage and low dropout single conductor, typical voltage drop of 32mV at 200mA current. Support maximum on-current of about 1A at 5V and current limit of about 1.3A. Support power supply voltage 2.2V~5.5V. Typical 20uS fast current limit protection in case of output over-current or output short-circuit. Diode chip shutdown to protect the load circuit at the output in case of input power polarity error. Low-power consumption, typical 4uA quiescent operating current. No reverse conduction current in diode chip off state. Available in SOT23-3, SOT23-6, and DFN6 packages. 1 PDF
