AS2702 – AS-Interface Slave IC
Revision 1.3, 21-Aug-08
Page 5 of 13
Buffer Pin CDC
An external buffer capacitor with a recommended value of 100nF should be connected to this pin to ensure a sufficiently high input
impedance Z at power supply pin LTGP.
Voltage at this pin can be as high as VLTGP.
Nom. 24V Power Supply Output UOUT
The supply output voltage at UOUT is directly derived from VLTGP and regulated to a level with an offset of about -6V relative to
VLTGP.
UOUT provides bias to the sensors and actuators circuitry connected to the slave device as well as to the LEDs connected to
outputs LED1 and LED2.
UOUT is equipped with a thermal overload protection, which foresees that VUOUT is switched off as soon as the slave device’s
substrate temperature TJ passes a threshold value in the range of (155
±
20)°C.
After TJ has come down and has passed a temperature threshold about (15
±
5)°C lower than (155
±
20)°C and after a consecutive
minimum delay time of 1s has elapsed, VUOUT is switched on again.

Notes:

In case IUOUT >40mA and presence of sin2-data pulses on LTGP with VSIG >3V, VUOUT may drop as much as 1V below it’s
level in unloaded condition

Nom. 5V Power Supply Output U5R
The voltage at U5R is derived from the voltage present at UOUT, as long as UOUT is not switched off due to overload. In the latter
case U5R is derived from an alternative voltage out of the UOUT voltage regulator, which is more or less similar to VUOUT in non
switched off condition of UOUT. As a result VU5R is not affected by overload condition at UOUT and will remain.
