WS7010AD
WS7010AD is High-side driver manufactured by Winsemi.
Description
High-side driver with current sense analog feedback for automotive applications
Features
General Description
- VCC pin：max transient supply voltage 40V
- Operating voltage range：4.5V to 28V
- WS7010AD is single channel high-side drivers with current 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
- WS7010AD integrates advanced protective functions such as
- On-state resistance Typ=12mΩ load current limitation, overload active management by power
- Thermal shutdown indication limitation and overtemperature shutdown with configurable
- OFF-state open-load detection latch-off. A Fault pin unlatches the output in case of fault or
- Overvoltage clamp disables the latch-off functionality.
- Undervoltage protection
- A dedicated multifunction multiplexed analog output pin
- Multiplexed analog feedback of: load current with high precision delivers sophisticated diagnostic functions including high proportional current mirror, VCC supply voltage and TCHIP device precision proportional load current sense, supply voltage temperature feedback and chip temperature sense, in addition to the
- Ro HS pliant and lead free detection of overload and short circuit to ground, short to VCC and OFF-state open-load.
- A sense enable pin allows OFF-state diagnosis to be disabled
Application during the module low power mode as well as external sense resistor sharing among similar devices.
- WS7010AD is available in DFN5×6-16L package.
- All types of automotive resistive, inductive and capacitive loads
- Specially intended for automotive signal lamps
