SMBus/I²C Interfaced 4-Port, Level-Translating GPIOs and LED Drivers
Low Operating Supply Voltage LED Drivers with Blinking, Transition Detection, and Level Translation in a Very Small Package Ideal for Cellular and Smartphone Applications
The MAX7306/MAX7307 I²C-/SMBus™-compatible, serial-interfaced peripherals feature four level-translating
I/Os and operate from a 1.62V to 3.6V power supply.
The MAX7307 features a port supply (VLA) that allows
level translation on I/O ports to operate from a separate
power supply from 1.4V to 5.5V. The MAX7306 features
an address select input (AD0) to allow up to four unique
slave addresses.
The MAX7306/MAX7307 ports P2, P3, and P4 can be
configured as inputs, push-pull outputs, and open-drain
outputs. Port P1 can be configured as a general-purpose
input, open-drain output, or an open-drain active-low INT output.
Ports P2 and P3 can be configured as OSCIN and
OSCOUT, respectively. The MAX7306/MAX7307 include
an internal oscillator for PWM, blink, and key debounce,
or to cascade multiple MAX7306/MAX7307s. The external
clock can be used to set a specific PWM and blink
timing. The active-low RST input asynchronously clears the 2-wire
interface and terminates a bus lockup involving the
MAX7306/MAX7307.
All ports configured as output feature 33-step PWM,
allowing any output to be set from fully off, 1/32 to 31/32
duty cycle, to fully on. All output ports also feature LED
blink control, allowing blink periods of 1/8 second, 1/4
second, 1/2 second, 1, 2, 4, or 8 seconds. Any port can
blink during this period with a 1/16 to 15/16 duty cycle.
The MAX7306/MAX7307 are specified over the -40°C to
+125°C temperature range and are available in 10-pin
µDFN (2mm x 2mm) and 10-pin µMAX® packages.
* Some packages have variations, listed on the drawing. "PkgCode/Variation" tells which variation the product uses. Note that "+", "#", "-" in the part number suffix describes RoHS status. Package drawings may show a different suffix character.
