The AFE539F1-Q1 is a 10-bit smart analog front end (AFE) targeted for constant power-dissipation control. The AFE539F1-Q1 can be used everywhere where constant power dissipation is desired on a resistive load independently on applied voltage. The AFE539F1-Q1 has an ADC input and a PWM output. This device has an integrated state machine that is preprogrammed as a constant power-dissipation controller. The AFE539F1-Q1 is an excellent choice for automotive DC-link capacitor discharge circuit and general constant-power-heating applications. The AFE539F1-Q1 works independently from parameters programmed into the NVM, which enable this smart AFE for processor-less applications and design reuse. This device also automatically detects I 2C or SPI, and has an internal reference.
