Description

PT7M6101/6102 series are designed for over current detector. They provide excellent circuit reliability and low cost by eliminating external components. These devices assert an OVRI signal when the voltage at IN pin rises above the high threshold. After IN pin declines below the low thre shold, OVRI signal is de-asserted. PT7M6101CL/6102CL have a push -pull active - low output. PT7M6101CH/6102CH have a push -pull active-high output. PT7M6101NL/6102NL ha ve an open-drain active -low output. The open -drain active - low output requires a pull -up res istor that can be connected to a voltage higher than VDD. Low supply current of 8 μA make s PT7M6101//6102 series ideal for using in battery power supply. These devices are available in SOT23-5 lead free packages.

Applications

 Over Current Protection in Battery Charger etc.  Over Temperature Protection  Power Supply  Voltage Monitoring Pin Description Pin Name I/O Description GND GND Ground OVRI O Over-current Output, Push-Pull or Open-Drain, Active-Low. OVRI changes from HIGH to LOW when IN rises above the typical high detection threshold (100mV). OVRI remains HIGH after IN drops below the low detection threshold (90mV). OVRI O Over-current Output, Push-Pull, Active-High. OVRI changes from LOW to HIGH when IN rises above the typical high detection threshold (100mV). OVRI remains LOW after IN drops below the low detection threshold (90mV). IN I Detection Voltage Input. High-impedance input for comparator. Connect this pin to over-current sampling network. OVRI is asserted when IN is above the high threshold voltage. VCC Power Supply Voltage
