The S-1003CA33I-I6T1U is a power management integrated circuit (PMIC) from ROHM Co., Ltd. It is a specialized supervisor IC (Supervisors) offering superior system protection and safety performance. It supports low standby current, wide input voltage range from 7V to 32V, a high-accuracy voltage detection function, and precision undervoltage monitoring for high-reliability applications.

The S-1003CA33I-I6T1U has a wide range of applications, such as automotive and industrial systems, medical equipment, and smart homes. It can protect sensitive devices from overvoltage and undervoltage by constantly monitoring the power supply and activating when the supply voltage is abnormal or out of range. This can help prevent malfunctions, failures, and other damages caused by the supply voltage irregularities.

When the supply voltage falls below the designated voltage level, the S-1003CA33I-I6T1U will detect the condition and switch off the power supply to protect the connected device. It also has an overvoltage protection feature with 5V to 32V input voltage range and tight tolerance of ±10%. This tight tolerance and wide input range enable it to protect the device from high-voltage conditions.

The S-1003CA33I-I6T1U also has a reset control output that is used to reset the system. When power is applied, the output enables the system to be restarted. This reset can be used for system reset or brownout reset. The reset control pin can also be used for external reset control from the MCU.

The S-1003CA33I-I6T1U has a standby current of as low as 10μA, making it highly suitable for battery-operated devices or applications where power consumption must be minimized. With its small size of 0.7mm x 2.2mm, it can fit into a small space in the system and enable a more compact design. The S-1003CA33I-I6T1U also offers a wide operating temperature range from -40°C to 125°C.

The S-1003CA33I-I6T1U includes a reverse current protection feature. It prevents any current leakage to the power source when the power source is disconnected. This helps to assure the safety of the system and the connected device.

The S-1003CA33I-I6T1U has an inverted output function, which allows the output to be switched on when the voltage improves. This enables the system startup or resume of operation even when an undervoltage occurs in the system. It is also capable of controlling the on/off control signal to the system, thereby enabling better system operation.

In conclusion, the S-1003CA33I-I6T1U is a powerful and versatile PMIC supervisor offering superior system protection and safety performance. It supports low standby current, a wide input voltage range, a high-accuracy voltage detection function, precision undervoltage monitoring, reverse current protection, and an inverted output function. With its high performance, small size, and extended operating temperature range, it is an ideal solution for a variety of automotive, industrial, medical, and smart home applications.
