WS7140S
WS7140S is High-side driver manufactured by WINSEMI.
Description
High-side driver with current sense analog feedback for automotive applications
Features
General Description
- WS7140S is single channel high-side drivers with current
- Operating voltage range：4.5V to 28V sense analog feedback for automotive applications, the devices
- Load current limitation are designed to drive 12 V automotive grounded loads through
- Output short-circuit protection a 3 V and 5 V.
- Standby current <1.0μA
- WS7140S integrates advanced protective functions such as
- On-state resistance Typ=145mΩ load current limitation, overload active management by power
- Thermal shutdown indication limitation and overtemperature shutdown.
- OFF-state open-load detection
- A dedicated multifunction multiplexed analog output pin
- Overvoltage clamp delivers sophisticated diagnostic functions including high
- Undervoltage protection precision proportional load current sense, in addition to the
- Multiplexed analog feedback of load current with high precision detection of overload and short circuit to ground, short to VCC proportional current mirror and OFF-state open-load.
- Ro HS pliant and lead free
- A sense enable pin allows OFF-state diagnosis to be disabled during the module low power mode as well as external sense
Application resistor sharing among similar devices.
- WS7140S is available in ESOP-8L package.
- All types of automotive resistive, inductive and capacitive loads
- Specially intended for automotive signal lamps
