MAX14900E
Octal, High-Speed, Industrial, High-Side Switch
General Description
The MAX14900E is an octal power switch that
features per-channel configuration for high-side or push-
pull operation. Low propagation delay, high-rate load-
switching makes the device suitable for next-generation
high-speed PLC systems. Each high-side switch sources
850mA continuous current with a low 165mΩ (max)
on-resistance at 500mA at T
A
= +125°C. The high-side
switches feature 2µs (max) input-to-output propagation
delay when driving resistive loads. Long cables can be
driven with switching rates of up to 100kHz for PWM/PPO
control in push-pull operation. Multiple high-side switches
can be connected in parallel to achieve higher drive
currents. The device features a wide supply input range
of 10V to 36V.
The MAX14900E is configured, monitored, and driven by
an SPI and/or parallel interface. In parallel mode, eight
logic inputs directly control the outputs and the serial
interface can be used for configuration/monitoring. Serial
mode utilizes the serial interface for both setting and
configuration, and features CRC error detection to ensure
robust SPI communication.
Current limiting and per-channel thermal shutdown
protect each switch/driver. The device features a global
diagnostics output as well as per-channel diagnostics and
monitoring through the serial interface.
The MAX14900E is available in a 48-pin (7mm x 7mm)
QFN-EP or standard 48-pin TQFN-EP package, and is
specified over the -40°C to +125°C temperature range.
