X4005S8Z-2.7 is a Precision Microcontroller Reset Supervisor with High Pulse Current for Power Reset in the PMIC-Supervisors category. This device is a reset supervisor that provides a fixed reset threshold voltage with positive pulse reset. The X4005S8Z-2.7 will reset the connected microcontroller when the supply voltage drops below the reset threshold. This device is designed to operate in conjunction with a separate supply Voltage Supervisory circuit (VSS) to reset the microcontroller during a power-on reset or a brown-out event.

The X4005S8Z-2.7 device is a high-current reset supervisor which can be used to reset an MCU (microcontroller), system processor or similarly powered device. It is designed to provide a constant reset threshold voltage and positive pulse reset with a minimum reset pulse width of 30µs. The reset pulse width is determined by an external resistor and capacitor. The X4005S8Z-2.7 has a high reset current capability of 100mA, allowing it to reset more complex and power-hungry microcontroller systems.

The X4005S8Z-2.7 is a single-column six-pad device with a 3x2mm footprint. It features a 6.2V operating voltage range, 500nA operating current, and a temperature range of -40°C to +85°C. The X4005S8Z-2.7 is fully AEC-Q100 certified, making it suitable for automotive applications. The device can be used with a variety of applications, such as automotive microcontroller reset supervisors, or in any other application where a microcontroller needs a reset.

The X4005S8Z-2.7 is designed to reset a microcontroller when the supply voltage drops below the reset threshold. The reset threshold is adjustable from 0.9V to 5V. The device has an internal 1.2V reference with a 4:1 voltage divider, allowing for a wide reset range with a minimum of external components. The reset output is guaranteed to remain active for a minimum of 30µs, allowing the connected microcontroller sufficient time to completely reset.

To ensure that the reset signal remains valid, the X4005S8Z-2.7 incorporates an internal reset glitch filter. This glitch filter detects extremely short reset pulses and eliminates them, ensuring the reset signal remains valid and the microcontroller is correctly reset. The X4005S8Z-2.7 also features a power enable (EN) input, allowing the device to be disabled while the system is powered off.

The X4005S8Z-2.7 is a versatile and reliable microcontroller reset supervisor that features a wide operating voltage range, high pulse current capability and a compact 3x2mm package. The device can easily be incorporated into a variety of applications where an MCU needs to be reset in the event of a power-on or brown-out reset condition. The device is fully AEC-Q100 certified and is suitable for automotive applications.
