Description
Analog input sets TEC cooling current protection limit.
Non-inverting input to error amplifier.
Inverting input to error amplifier.
Output of error amplifer.
Non-inverting input to compensation amplifier.
Inverting input to compensation amplifier.
Output of compensation amplifier.
2.5V Voltage Reference output.
Power for non-driver sections. 3.0 V min; 5.5V max.
Sets SYNCOUT clock phase relative to SYNCIN clock.
Indicates when thermistor temperature is within ±0.01°C if target temperature as
set by TEMPSET voltage.
Analog ground. Connect to low noise ground.
Sets switching frequency with an external resistor.
Sets soft-start time for output voltage. Pull low to put ADN8831 into standby mode
(VTEC = 0V).
Phase adjustment clock output. Phase set from PHASE pin. Used to drive SYNCIN of
other ADN8831 devices.
Optional clock input. If not connected, clock frequency is set by FREQ pin. Pull low
to put ADN8831 into shutdown mode.
Comensation for oscillator; connect capacitor to ground.
Power for output driver sections. 3.0V min; 5.5V max.
Drives PWM output external PMOS gate.
Connects to PWM FET drains.
Drives PWM output external NMOS gate.
Power ground. External NMOS devices connect to PGND. Connect to digital ground.
PWM feedback. Typically connects to TEC- pin of TEC.
Comensation for switching amplifier.
Drives linear output external PMOS gate.
Drives linear output external NMOS gate.
Linear feedback. Will typically connect to TEC+ pin of TEC.
Connect to output current sense resistor.
Indicates TEC current.
Indicates TEC voltage.
Sets maximum TEC voltage.
Sets TEC heating current protection limit.
