PCA9632
4-bit Fm+ I 2 C-bus low power LED driver
4. Once the SWRST Call address has been sent and acknowledged, the master sends
2 bytes with 2 specific values (SWRST data byte 1 and byte 2):
a. Byte 1 = A5h: the PCA9632 acknowledges this value only. If byte 1 is not equal to
A5h, the PCA9632 does not acknowledge it.
b. Byte 2 = 5Ah: the PCA9632 acknowledges this value only. If byte 2 is not equal to
5Ah, then the PCA9632 does not acknowledge it.
If more than 2 bytes of data are sent, the PCA9632 does not acknowledge any more.
5. Once the right 2 bytes (SWRST data byte 1 and byte 2 only) have been sent and
correctly acknowledged, the master sends a STOP command to end the SWRST Call:
the PCA9632 then resets to the default value (power-up value) and is ready to be
addressed again within the specified bus free time (t BUF ).
The I 2 C-bus master must interpret a non-acknowledge from the PCA9632 (at any time) as
a ‘SWRST Call Abort’. The PCA9632 does not initiate a reset of its registers. This
happens only when the format of the SWRST Call sequence is not correct.
7.6 Using the PCA9632 with and without external drivers
The PCA9632 LED output drivers are 5.5 V only tolerant and can sink up to 25 mA at 5 V.
If the device needs to drive LEDs to a higher voltage and/or higher current, use of an
external driver is required.
? INVRT bit (MODE2 register) can be used to keep the LED PWM control firmware the
same (PWMx and GRPPWM values directly calculated from their respective formulas
and the LED output state determined by LEDOUT register value) independently of the
type of external driver.
? OUTDRV bit (MODE2 register) allows minimizing the amount of external components
required to control the external driver (N-type or P-type device).

Correct configuration when LEDs directly connected to the LEDn outputs (connection to V DD through current limiting resistor).
Optimum configuration when external N-type (NPN, NMOS) driver used.
Optimum configuration when external P-type (PNP, PMOS) driver used.
