3 Description

The 8-bit AFE439A2, 10-bit AFE539A4, and 12-bit

AFE639D2 (AFEx39xx) are smart analog front ends

(AFE) for thermoelectric cooling (TEC) control using

voltage or PWM output. The AFE639D2 supports an

I2C controller interface to interface with external digital

temperature sensors. The AFE639D2 and AFE539A4

support voltage output and AFE439A2 supports PWM

output. The AFEx39xx support a comparator channel

for fault management. These devices also support

Hi-Z power-down mode and Hi-Z output on the DAC

channel during power off. These devices have an

integrated state machine that is preprogrammed as

a proportional-integral (PI) controller. The AFEx39xx

are an excellent choice for TEC control, temperature

control, and dynamic headroom control applications.

The AFEx39xx integrate advanced features, internal

reference, and NVM that enable this smart AFE for

processor-less applications and design reuse.
