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 threshold, 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 have an open-drain
active-low output. The open-drain active-low output
requires a pull-up resistor that can be connected to a
voltage higher than VDD.
Low supply current of 8µA makes PT7M6101//6102
series ideal for using in battery power supply. These
devices are available in SC70-4, SOT23-5, TO94 lead
free packages.
Application
• Over Current Protection in Battery Charger etc.
• Over Temperature Protection
• Power Supply
• Voltage Monitoring

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.

Functional 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 threshold, OVRI signal is de-asserted.
