MAX22288
Home Bus System (HBS) Compatible
Transceiver
General Description
Benefits and Features
The MAX22288 Home Bus System (HBS) compatible
transceiver can be used in the Home Bus System, where
data and power are passed on a single pair of wires
while minimizing the need for external components.
• Robust Communication with Configurability
• Dynamic Cable Termination Improves Signal
Quality for High-Speed Applications
• Adjustable Slew Rates for Low EMI
• Maximum Data Rate up to 200kbps over 1000m
UTP Cable
• Programmable Receiver Thresholds
• Space Saving
• 4mm x 4mm TQFN package
The MAX22288 provides robust communication by
using dynamic cable termination that improves the
signal quality with longer cables and higher data rates.
The device data outputs AIO/BIO do not load the bus
when the MAX22288 is not powered. The MAX22288
supports passing data with speed up to 200kbps.
• Pin-to-pin Compatible with the MAX22088
• Integrated Protection
The MAX22288 features adjustable receiver thresholds
and driver slew rates that allow the MAX22288 to be
used in a wide variety of systems. Integrated protection
ensures robust communication in harsh industrial
environments.
• IEC 61000-4-2 ±8kV Contact and ±15kV Air-Gap
ESD Protection
• IEC 61000-4-5 ±1kV Transient Surge Protection
with Selected External Components
• -40°C to +125°C Operating Temperature Range
The MAX22288 is pin-to-pin compatible with the
MAX22088, the Home Bus System (HBS) Compatible
Transceiver with Active Inductor. The MAX22288 is
recommended for use in an HBS system where an
external power supply is typically available.

MAX22288
Home Bus System (HBS) Compatible Transceiver
Detailed Description
The MAX22288 can be used in the Home Bus System (HBS), where power and data are carried on a single pair of wires.
The MAX22288 operates with data rates up to 200kbps for bus-powered applications. The MAX22288 is used in HBS
applications where external power supplies are sourced. In HBS applications where power is consumed, the MAX22088,
a HBS compatible transceiver with active inductor, can be used. Refer to the MAX22088 data sheet for more information.
The MAX22288 features dynamic cable termination, configurable receiver thresholds, and transmit driver slew rate
adjustment for better signal quality and flexible design.
Power Supply
The MAX22288 is powered by the external 5V (typ) supplied at VCC. An external inductor and coupling capacitors are
required to superimpose the data on the HBS cable.
Operation of MAX22288 Transceiver
The MAX22288 uses three pins for the logic interface: RST, DIN, and DOUT. AIO, BIO, and TERM are connected to the
HBS network. RST is the bus reset control input. Drive RST low to enable the transmitter on AIO and BIO. Drive RST
high to disable the transmitter. The MAX22288 HBS receiver is always enabled.
DIN is the logic input of the MAX22288. DOUT is the logic output. When DIN goes from high to low, the polarities of AIO
and BIO invert. When DIN goes from low to high, AIO and BIO are set to high-impedance (Figure 5).
DOUT asserts low when the leading edge of V
- V
crosses V
or -V
. DOUT is high-impedance when the
TVL

or -V . See the Receiver Threshold Adjustment section for more information.

AIO
BIO
To improve signal quality, the MAX22288 features an internal switch that connects TERM to AIO for 34μs (typ) after the
driver transitions to high-impedance. See the Dynamic Cable Termination section for more information.
For a typical data rate of 57.6kbps, the recommended value for coupling capacitors is 2.2µF (min).

MAX22288
Home Bus System (HBS) Compatible Transceiver
Dynamic Cable Termination
The MAX22288 supports HBS signals at data rates up to 200kbps. When operating at high data rates, the mismatch
between the HBS cable impedance and cable termination resistor can negatively affect the signal quality. The MAX22288
features dynamic cable termination to improve the signal quality with longer cables. When the driver transitions to high-
impedance, an internal switch connects AIO to TERM. The external termination resistor at TERM is then connected
between AIO and BIO in parallel with the static cable termination resistor. The internal switch opens after 34μs (typ), when
DOUT asserts low, or when RST is driven high. The optimized value of the dynamic termination resistor depends on the
application. For typical applications, the value of the dynamic termination resistor is between 50Ω and 240Ω.
Transmit Slew Rate Adjustment
Connect an external resistor R
from SRA to GND to control the slew rate of the transmit signals at AIO and BIO. The
SRA
transmit rise/fall time (t
, t
, t
, t
) is proportional to R
and is calculated using the following equation:
RLD FLD RTR FTR
SRA
(ns) = 17pF × R
t
(kΩ)
rise/fall
SRA
For most applications, it is recommended to use R
= 62kΩ resulting in 1μs (typ) output rise/fall time. Ensure that
SRA
R
is in the range from 33kΩ to 470kΩ.
SRA
Receiver Threshold Adjustment
The threshold levels for the receiving signals are set by the voltages at TVL and TVT. The voltage at TVL sets the
threshold for the leading edge of the pulse on the Home Bus signal (V - V ). The voltage at TVT sets the threshold
AIO

for the trailing edge of the pulse. Ensure that V

MAX22288
Home Bus System (HBS) Compatible Transceiver
RST (Reset) Functionality
The MAX22288 features a bus reset control input. Drive RST low to enable the transmitter. Drive RST high to disable the
transmitter. RST also controls the internal switch used for dynamic cable termination. Ensure that RST remains low for at
least 34μs (typ) after the internal switch is closed when the driver transitions to high-impedance. The internal switch opens
when RST is driven high.
High-Pass Filter
The MAX22288 features an internal high-pass filter on the receiver to filter out the low frequency voltage fluctuations at
AIO and BIO. Connect
to GND to enable the internal high-pass filter on the receiver input. Connect
to VCC
to disable the internal high pass filter. Ensure that
is always connected.
Watchdog Timer Functionality
The MAX22288 features an internal watchdog timer to avoid the bus being blocked by a long zero. This feature is enabled
by setting to low. The internal watchdog timer monitors the logic input DIN and if any long zero condition persists
for more than 21ms (typ) and blocks the bus, it sets the AIO and BIO outputs to high-impedance states. Any transition
resets the watchdog timer. has a weak internal pulldown to ground.

Applications Information
Surge Protection
External components are required to protect the MAX22288 Home Bus pins (AIO, BIO, and TERM) from high-voltage
transient events. The Typical Application Circuit shows a recommended protection scheme.
AIO, BIO, and TERM Surge Protection
AIO, BIO, and TERM must be protected with external components from surge transients. Connect TVS diodes with a 5.8V
(max) standoff voltage from AIO and BIO to GND. Connect a 4.7Ω serial resistor between each TVS diode and AIO/BIO
to limit the current flows into AIO/BIO during the surge transients. Depending on the surge transient polarities, the residual
current after the 4.7Ω resistor flows from AIO/BIO through the internal ESD clamping diodes to VCC or GND. Connect a
1μF (min) ceramic capacitor as close to VCC as possible, and a 10μF (min) bulk capacitor on the VCC bus to absorb this
current and limit the voltage overshoot on VCC during surge transients.
Layout Recommendations
To ensure proper protection, connect the ground return of the protection diodes directly to the ground plane. Use a star
configuration to connect all grounds together as close to the GND (pin 9) as possible. Place the external protection TVS
diodes and the diode bridge as close to the Home Bus connector as possible.
Application Notes
Refer to AN7224, Introduction to Home Bus, for Home Bus System (HBS) standard and communication protocols.
Refer to AN7226, How to Transmit UART Packets Using Home Bus System (HBS) Compatible Transceiver, for data
packet processing examples in a microcontroller in the Home Bus System.
