MAX14918AATG+規(guī)格書詳情
General Description
The MAX14918 and MAX14918A are quad 700mA lowside
switches for industrial applications. Each device
features four 140mΩ (typ) on-resistance (RON) switches
with integrated ±1.2kV/42Ω surge protection. Two or
more outputs can be connected in parallel to provide
higher load current.
The maximum load current is actively limited and is
resistor settable between 100mA (typ) and 900mA (typ).
For load that draws high inrush current, the MAX14918
and MAX14918A have the inrush mode which provides
2x current after switch turn-on for 10ms (min).
The MAX14918 has an SPI allowing control of multiple
MAX14918 devices through a common daisy-chained
interface for high channel-count applications, minimizing
galvanic isolation channels. Per-channel diagnostics are
returned on the serial data output (SDO). Data
corruption on the serial data input (SDI) is automatically
detected and signaled on the SPIFLT output.
The MAX14918A offers a pin-based switch control with
a latch option (LATCHEN) which allows sharing of the
four IN_ control signals among multiple MAX14918A
devices.
Slew rate control provides controlled turn-on edge for
reducing electromagnetic interference or EMI emissions.
Simultaneously, a global DIS control signal allows
disabling of all OUT_ switches quickly.
The integrated 5V low dropout (LDO) regulator in the
MAX14918 and MAX14918A can be used to power
external isolators or other logic circuitry.
