PRODUCTION DATA
Built-in self-diagnostic features are incorporated in the TMCS1133-Q1 to warn when operating conditions invalidate current sensor measurements. Two critical conditions being monitored are sensor temperature and sensitivity.
As discussed in the Safe Operating Area section, high levels of input current can generate excessive heat inside the TMCS1133-Q1. High input currents, coupled with elevated ambient temperatures and printed circuit board thermal design can cause the TMCS1133-Q1 to overheat and be permanently damaged by exceeding maximum allowed junction temperatures. A thermal alert occurs when the internal temperature approaches the maximum allowed junction temperature.
In addition to temperature, sensor sensitivity and offset are constantly being monitored inside the TMCS1133-Q1. A sensor alert occurs in the unlikely event Hall sensor sensitivity or offset is out of range compared with factory set limits.
