MAX4896ETP+
Space-Saving, 8-Channel Relay/Load Driver
General Description
The MAX4896 8-channel relay and load driver is designed
for medium voltage applications up to 50V. This device is
offered in a 20-pin, 5mm x 5mm TQFN package, resulting
in substantial board space savings.
The MAX4896 8-channel relay driver offers built-in induc-
tive kickback protection, drive for latching/nonlatching
or dual-coil relays, and open-load and short-circuit fault
detection.The MAX4896 also protects against overcur-
rent conditions. Each independent open-drain output fea-tures a 3Ω (typ) on-resistance, and is guaranteed to sink 200mA of load current (VS ≥ 4.5V).
A built-in overvoltage protection clamp handles kickback-
voltage transients, which are common when driving induc-
tive loads. Thermal-shutdown circuitry shuts off all outputs (OUT_) when the junction temperature exceeds +160°C.
The MAX4896 employs a reset input that allows the user to
turn off all outputs simultaneously with a single control line.
The MAX4896 includes a 10MHz SPI™-/QSPI™-/ MICROWIRE™-compatible serial interface. The serial inter-face is compatible with TTL-/CMOS-logic voltage levels and operates with a single +2.7V to +5.5V supply. In addition, the SPI output data can be used for diagnostics purposes
including open-load and shortcircuit fault detection.
The MAX4896 is offered in the extended (-40°C to +85°C) and automotive (-40°C to +125°C) operating temperature ranges.

Note 1: Maximum continuous current at a given temperature must be calculated such that the maximum continuous power dissipation
for the package is not exceeded.
Note 2: Package thermal resistances were obtained using the method described in JEDEC specification JESD51-7, using a four-layer
board. For detailed information on package thermal considerations, refer to www.maximintegrated.com/thermal-tutorial.
Absolute Maximum Ratings
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these
or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect
device reliability.

pulldown currents are disabled when RESET = low.CSChip Select Input. Drive CS low to select the device. When CS is low, data at DIN is clocked into the8-bit shift register on SCLK’s rising edge. Drive CS from low to high to latch the data to the registers.DINSerial Data InputSCLKSerial Clock InputDOUTSerial Data Output. DOUT is the output of the 8-bit shift register. This output can be used to daisy chain multiple MAX4896s. The data at DOUT appears synchronous to SCLK’s falling edge.PDCDPulldown Current Disable. Drive PDCD high to disable OUT’s pulldown current source. Drive PDCD low to enable OUT_ pulldown current source. PDCD must be low to detect an open-load fault.SPLDShort-Protection Latch-Off Disable Input. Drive SPLD high to disable the built-in short-circuit protection latch-off feature.
