8.4. ASC Temperature Monitor
The ASC has two external Temperature Monitors (TMONs) which both are connected to on board temperature sensors
as listed in
Table
8.4. One TMON is connected to a PNP transistor as shown in
connected to an NPN transistor as shown in
shown on the schematic as close to the transistors. However, they are physically close to the L-ASC10 (U7).
