SP6330/32/34 Quad Power Supervisory Circuit Family

The SP6330, SP6332, and SP6334 include

a low-voltage precision bandgap reference,

four precision comparators, an oscillator, a

digital counter chain, a logic control block,

trimmed resistor divider chains and

additional supporting circuitry. The family is

designed to supervise up to 4 independent

supply voltages. V1 and V2 supply inputs

have their resistor dividers on the chip.

Their trip thresholds are factory trimmed.

V3 and V4 inputs allow user to customize

THEORY OF OPERATION

two additional supply thresholds to be

monitored by means of external resistor

dividers. The devices also feature manual

reset and watchdog functionalities.

As these devices do not have watchdog

outputs, the watchdog timer is serviced

internally during the watchdog timeout

period when WDI is left unconnected. The

watchdog functionality can be disabled by

leaving the WDI input floating.
