• Description: Supervisory IC with I2C Interface and PWM
• Manufacturer: SEMTECH [Semtech Corporation]

Dual Drive Digital Bidirectional: INT
This is a bi-directional digital pad with optional High or Low output drive strengths. It includes a Schmitt input stage.
The pin may be used either as the Interrupt output or as a general-purpose I/O (GPIO).
Low drive strength is implemented as a pull-up or pull-down impedance to allow the pin to be overdriven by an external
source if required. Supply is VDD and the pad includes diode protection to VDD and GND.

POWER MANAGEMENT
Pad Specifi cations
Note: If the INT pin is programmed as a GPIO input (default
state), it must be tied high (VDD) or low (GND) to ensure that a
fl oating input does not cause excessive current consumption
in the digital input stage.
