Thermal Diode on TSMC CLN40G

Overview

The ABIBJT40 remote thermal diode macro is implemented using bipolar and 1.8V IO devices. The diode is a core macro intended to be used with analog IO pads and low-resistance interconnect (not included). The diode is designed to work with popular temperature sensors, like the MAX6557/6658/6659 from Maxim.

In order to maximize ease of use, the diode incorporates a proprietary ESD structure, which is proven in several generations of processes. The ESD protection within the thermal diode core is supplemental – primary protection should be in the IO pads. In the case that the IO pads are close to the Thermal Diode (less than 1 Ohm away for A, K and VSS connections) then the ESD structure within the diode may be used as the primary ESD protection (no additional ESD protection required).
