• Manufacturer Part Number: cat6095
• Description: Digital Output Temperature Sensor
• Manufacturer: ON Semiconductor

PIN DESCRIPTION
SCL: The Serial Clock input pin accepts the Serial
Clock generated by the Master (Host).
SDA: The Serial Data I/O pin receives input data
and transmits data stored in the internal registers. In
transmit mode, this pin is open drain. Data is
acquired on the positive edge, and is delivered on
the negative edge of SCL.
A0, A1 and A2: The Address pins set the device
address. These pins have on-chip pull-down
resistors and will default to an address of 000 if left
unconnected.

EVENT
programmed to signal over/under temperature limit
conditions.
POWER-ON RESET (POR)
The CAT6095 incorporates Power-On Reset (POR)
circuitry which monitors the supply voltage, and then
resets (initializes) the internal state machine below
(above) a POR trigger level of approximately 1.2 V,
i.e. well below the minimum recommended V
value.
The TS powers-up into conversion mode. The
internal state machine will operate properly above
the POR trigger level, but valid temperature readings
can be expected only after the first conversion cycle.
DEVICE INTERFACE
The CAT6095 supports I
transmission protocols. These protocols describe
serial communication between transmitters and
receivers sharing a 2-wire data bus. Data flow is
controlled by a Master device, which generates the
serial clock and the START and STOP conditions.
The CAT6095 acts as a Slave device. Master and
Slave alternate as transmitter and receiver. Up to 8
CAT6095 devices may be present on the bus
simultaneously, and can be individually addressed
by matching the logic state of the address inputs A0,
A1, and A2.
