8 / 31 page Dual, Temperature-Controlled Resistors with Inter- nally Calibrated Monitors and Password Protection 8 _____________________________________________________________________ Detailed Description The user can read the registers that monitor the VCC, MON1, MON2, MON3, and temperature analog signals. After each signal conversion, a corresponding bit is set that can be monitored to verify that a conversion has occurred. The signals also have alarm and warning flags that notify the user when the signals go above or below the user-defined value. Interrupts can also be set for each signal. The position values of each resistor can be indepen- dently programmed. The user can assign a unique value to each resistor for every 2°C increment over the -40°C to +102°C range. Two buffers are provided to convert logic-level inputs into open-drain outputs. Typically, these buffers are used to implement transmit (Tx) fault and loss-of-signal (LOS) functionality. Additionally, OUT1 can be asserted in the event that one or more of the monitored values go beyond user-defined limits. PIN BALL NAME FUNCTION 1B2 SDA 2-Wire Serial Data I/O Pin. Transfers serial data to and from the device. 2A2 SCL 2-Wire Serial Clock Input. Clocks data into and out of the device. 3C3 OUT1 Open-Drain Buffer Output 4A1 IN1 TTL/CMOS-Compatible Input to Buffer 5B1 OUT2 Open-Drain Buffer Output 6C2 IN2 TTL/CMOS-Compatible Input to Buffer 7C1 N.C. No Connection 8D1 GND Ground 9D3 MON1 External Analog Input 10 D4 MON2 External Analog Input 11 C4 MON3 External Analog Input 12 D2 L0 Low-End Resistor 0 Terminal. It is not required that the low-end terminals be connected to a potential less than the high-end terminals of the corresponding resistor. Voltage applied to any of the resistor terminals cannot exceed the power-supply voltage, VCC, or go below ground. 13 B3 H0 High-End Resistor 0 Terminal. It is not required that the high-end terminals be connected to a potential greater than the low-end terminals of the corresponding resistor. Voltage applied to any of the resistor terminals cannot exceed the power-supply voltage, VCC, or go below ground. 14 B4 L1 Low-End Resistor 1 Terminal 15 A4 H1 High-End Resistor 1 Terminal 16 A3 VCC Supply Voltage Pin Description |
