Redesign the circuit to:

1. Create a single threshold point for changing the TEC bias level. The old design had two threshold levels occuring

at VDD equal to 3.5V and 4.5V. The new design has a single threshold level occuring at VDD equal to 4.0V.

2. Remove the fault protection mode. This mode of operation has been removed from the product.

1. It was found that on some designs and layouts, the device would transition the TEC bias point during a start up or

transient condition when VDD momentarily dipped below the threshold voltage. By eliminating the second

threshold point and shifting the new single threshold from 4.5V to 4.0V, this problem has been eliminated.

2. It was also found on some designs that if the TEC bias point shifted as VDD changed, the part could erroneously

enter into a fault mode and not recover. By removing the fault detection, this problem has been eliminated.
