LMD18400 Overview
The LMD18400 is a fully protected quad high side driver. It contains four mon-drain DMOS N-channel power switches, each capable of switching a continuous 1 Amp load (>3 Amps transient) to a mon positive power supply. The switches are fully protected from excessive voltage, current and temperature.
LMD18400 Key Features
- 2 Four independent outputs with >3A peak, 1A continuous current capability
- 1.3Ω maximum ON resistance over temperature
- True instantaneous power limit for each switch
- High survival voltage (60 VDC, 80V transient)
- Shorted load (to ground and supply)
- Overvoltage shutdown at VCC > 35V
- LS TTL/CMOS patible logic inputs and
- <10 µA supply current in “sleep” mode
- 5V output clamp for discharging inductive
- Serial data interface for 11 diagnostic checks
