MX5114E
Single 15A Peak Current Laser Driver
WUXI MAXIN MICRO 1 / 8 无锡明芯微电子有限公司
GENERAL DESCRIPITION
The MX5114E is designed to drive a VCSEL with strong sink
current capability from an internal N-MOSFET. The
MX5114E provides inverting and noninverting inputs to
satisfy requirements for inverting and noninverting input. The
inputs of the MX5114E are TTL/CMOS Logic compatible and
withstand input voltages up to 18 V regardless of the VDD
voltage. The MX5114E has fast switching speed and
minimized propagation delays, facilitating high-frequency
operation. The MX5114E is available in a 6-pin SOT23-6
package.
FEATURES
♦ 4V to 20V Single Power Supply
♦ 15A Peak Current Transient
♦ 0.4Ω turn on resistance with internal FET
♦ 5ns (Typical) Propagation Delay
♦ Matching Delay Time Between Inverting and
Noninverting Inputs
♦ TTL/CMOS Logic Inputs
♦Low Input Capacitance: 2.5pF (Typical)
♦–40°C to 125°C Operating Temperature Range
♦ 6-Pin SOT23-6L
APPLICATIONS
Laser driver without external MOSFET
