PCA9632
4-bit Fm+ I
2
C-bus low power LED driver
The Software Reset (SWRST) Call allows the master to perform a reset of the PCA9632
through the I
2
C-bus, identical to the Power-On Reset (POR) that initializes the registers to
their default state causing the outputs to be set high-impedance. This allows an easy and
quick way to reconfigure all device registers to the same condition.
2. Features and benefits
40 power reduction compared to PCA9633
4 LED drivers. Each output programmable at:
Off
On
Programmable LED brightness
Programmable group dimming/blinking mixed with individual LED brightness
1 MHz Fast-mode Plus I
2
C-bus interface with 30 mA high drive capability on SDA
output for driving high capacitive buses
256-step (8-bit) linear programmable brightness per LED output varying from fully off
(default) to maximum brightness using a 1.5625 kHz PWM signal in Individual
brightness mode
64-step (6-bit) linear programmable brightness for each LED output varying from fully
off (default) to maximum brightness using a 6.25 kHz PWM signal in group dimming
mode
In group dimming mode, 16-step group brightness control allows global dimming
(using a 190 Hz PWM signal) from fully off to maximum brightness (default)
256-step (8-bit) linear programmable brightness per LED output varying from fully off
(default) to maximum brightness using a 1.5625 kHz PWM signal in group blinking
mode
64-step group blinking with frequency programmable from 24 Hz to 6 Hz and
duty cycle from 0 % to 98.4 %
256-step group blinking with frequency programmable from 6 Hz to 0.09 Hz (10.73 s)
and duty cycle from 0 % to 99.6 %
Four totem pole outputs (sink 25 mA and source 10 mA at 5 V) with software
programmable open-drain LED outputs selection (default at high-impedance). No input
function.
10-pin package option provides two hardware address pins allowing four devices to
operate on the same bus
Output state change programmable on the Acknowledge or the STOP Command to
update outputs byte-by-byte or all at the same time (default to ‘Change on STOP’).
Software Reset feature (SWRST Call) allows the device to be reset through the
I
2
C-bus
400 kHz internal oscillator requires no external components
Internal power-on reset
Noise filter on SDA/SCL inputs
Edge rate control on outputs
No glitch on power-up
Supports hot insertion
Low standby current of < 1 A
Operating power supply voltage range of 2.3 V to 5.5 V
