Editing Thermal sensors

== Overview ==
The PS2 has a thermal sensor IC in proximity to the EE (or EE+GS, depending on the revision).

On consoles with a Dragon [[MechaCon]] (SCPH-5XXXX and later), the thermal sensor is connected to the MechaCon and the temperature can be read from software. On earlier consoles, the thermal sensor is connected to the [[SysCon]] and the temperature can (currently) not be read from software. GH-001 and GH-003 use a simple thermostat instead of a temperature sensor.

== Texas Instruments LM56 ==
Thermostat, 2 digital outputs for 2 configurable temperature thresholds, used in conjunction with NJM062V op-amp

Used on GH-001 and GH-003

== Texas Instruments LM74 ==
SPI/Microwire temperature sensor, 13 bit, 8-pin SOIC-8

Used on GH-004, GH-005, GH-006, GH-007, GH-008, GH-010, GH-012, GH-013, GH-014

== Texas Instruments LM70 ==
SPI/Microwire temperature sensor, 11 bit, 8-pin VSSOP-8

Used on GH-015, GH-016, GH-017, GH-019, GH-022

== Texas Instruments LM71 ==
SPI/Microwire temperature sensor, 14 bit, 5-pin SOT-23, SMD-code: T16C. Some boards that use the LM71 also have alternate solder pads and wiring for a LM20.

Used on GH-023, GH-026, GH-029, GH-032, GH-035, GH-036, GH-037, GH-040, GH-041

== Texas Instruments LM20 ==
Analog output temperature sensor, 5-pin SOT-323/SC-70, SMD-code: T2B. Analog output connected to Dragon-[[MechaCon]], which probably has an internal ADC for this. Some boards that use the LM20 also have alternate solder pads and wiring for a LM71.

Used on GH-051, GH-052, GH-061, GH-062 (also likely on GH-070, GH-071, GH-072, but unconfirmed)

== Seiko S-58LM20A ==
Analog output temperature sensor, 4-pin SC-82AB, SMD-code: DRE. Analog output connected to Dragon-[[MechaCon]], which probably has an internal ADC for this. Drop-in replacement for Texas Instruments LM20 that can be mounted on the same footprint with 1 pin less (which is NC on Texas Instruments LM20).

Used on GH-072 (also likely on GH-070, GH-071, but unconfirmed)

== PS2 hardware in PS3 ==
[https://www.psdevwiki.com/ps3/COK-00x COK-001] has unpopulated pads for a thermal sensor next to EE+GS. COK-002 doesn't have any temperature monitoring capabilities next to GS.
