Pin Configuration

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

Low

current

of

8μA

makes

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

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.
