NAME
FUNCTION
Power-Save Control. Connect a timing capacitor from PSAVE to ground. The capacitor
value determines power-save timing as explained under the Applications Information

PSAVE
section. PSAVE can also be driven externally to control power-save mode
asynchronously. When PSAVE is asserted high, the current through the coils is reduced
to 60% of the initial nominal current value. To disable power-save mode in all channels,
drive PSAVE low for at least 3ms after last output setting.

Open-Drain Output 4. Connect OUT4 to the low side of a relay coil. This output is pulled
to PGND when activated, but otherwise is high impedance.
Open-Drain Output 3. Connect OUT3 to the low side of a relay coil. This output is pulled
to PGND when activated, but otherwise is high impedance.
Open-Drain Output 2. Connect OUT2 to the low side of a relay coil. This output is pulled
to PGND when activated, but otherwise is high impedance.
Open-Drain Output 1. Connect OUT1 to the low side of a relay coil. This output is pulled
to PGND when activated, but otherwise is high impedance.
Input Supply Voltage. Bypass V CC to GND with a 0.1μF capacitor.
Set Input. Drive SET low to set all latches and registers high (all outputs are low

Detailed Description
Serial Interface (MAX4822/MAX4823)
Depending on the MAX4822/MAX4823 device, the serial
interface can be controlled by either 8- or 16-bit words
as depicted in Figures 1 and 2. The MAX4823 does not
support power-save mode, so the serial interface con-
sists of an 8-bit-only shift register for faster control.
The MAX4822 consists of a 16-bit shift register and par-
allel latch controlled by SCLK and CS . The input to the
shift register is a 16-bit word. In the MAX4822, the first
8 bits determine the register address and are followed
by 8 bits of data as depicted in Figure 1. Bit A7 corre-
sponds to the MSB of the 8-bit register address in
Figure 1, while bit D7 corresponds to the MSB of the 8
bits of data in the same Figure 1.
The MAX4823 consists of an 8-bit shift register and par-
allel latch controlled by SCLK and CS . The input to the
shift register is an 8-bit word. Each data bit controls
one of the eight outputs, with the most significant bit
(D7) corresponding to OUT8, and the least significant
bit (D0) corresponding to OUT1 (see Figure 2).
