MikroElektronika High-Side Switch Controller with Intelligent E-Fuse Protection From STMicroElectronic MOSFET for

The MikroElektronika High-side switch Controller with intelligent fuse protection is an advanced controller for a power MOSFET in high side configuration, designed for the implementation of an Intelligent High Side Switch for 12 V, 24 V and 48 V automotive applications. The Control IC is interfaced to a host microcontroller through a 3.3 V and 5 V CMOS-compatible SPI interface and provides protection and diagnostics to the system.

• SPI slave interface for host control
• 32 bit ST SPI interface compatible with 3.3 V and 5 V CMOS level
• 2 stage charge pump
• Gate drive for an external MOSFET in high side configuration
• High precision unidirectional digital current sense via SPI through an external high side shunt resistor
• Input for a NTC resistor to monitor the external MOSFET temperature
• Very low standby current
• Robust fail safe functionality through internal and external controls
• SPI register lock out by a dedicate digital input pin
