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 V
DD
.

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).
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).
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.
