CAT9532
External Reset Operation
The CAT9532 registers and the I 2 C state machine are
initialized to their default state when the RESET input is
held low for a minimum of t W . The external Reset timing is
shown in Figure 13.
LED Output Operation
Figure 11 shows typical current values for LED pin
voltages at various case temperatures.

Power ? On Reset Operation
The CAT9532 incorporates Power ? On Reset (POR)
circuitry which protects the internal logic against powering
up in the wrong state. The device is in a reset state for V CC
less than the internal POR threshold level (V POR ). When
V CC exceeds the V POR level, the reset state is released and
the CAT9532 internal state machine and registers are
initialized to their default state.
