The sink current is set by the resistor connected from FREQ
(Pin 13) to ground. The sink current is calculated using the
following equation:
1.25 V
R FREQ
w here:
I SINC is the sink current at VLIM (Pin 31).
R FREQ is the resistor connected at FREQ (Pin 13).
The cooling and heating limits are calculated using the
following equations:
Data Sheet
MAXIMUM TEC CURRENT LIMIT
To protect the TEC, separate maximum TEC current limits in
cooling and heating directions are set by applying a voltage at
ILIMC (Pin 1) and ILIMH (Pin 32). Maximum TEC currents
are calculated using the following equations:
V ILIMC ? 1.25 V
25 × R SENSE
1.25 V ? V ILIMH
25 × R SENSE
V VLIM , COOL =
V REF × R B
R A + R B
V VLIM , HEAT = V VLIM , COOL ? I SINK × R A R B
