CT432 & CT433 XtremeSense® TMR Current Sensors
Allegro MicroSystems CT432 and CT433 XtremeSense® TMR Current Sensors are integrated contact current sensors with high bandwidth and ultra-low noise. The Allegro MicroSystems CT432 and CT433 utilize Crocus Technology’s XtremeSense® TMR technology. XtremeSense provides precise current measurements for various consumer, enterprise, and industrial uses, supporting multiple current ranges up to 65A. The sensor delivers a linear analog output voltage with a total output error of less than ±1.0% full-scale (FS) over the supply voltage and temperature range. The devices boast a 300ns output response time, 6.0mA current consumption, and immunity to common mode fields. Optimized for high dV/dt applications, the sensors minimize capacitive coupling to VOUT for switching applications.
