The S-1009C34I-I4T1U, classified as a PMIC supervisor, is an ultra-small, low power sot-23 regulator used for system supervision. This device operates on the three-pin SOT-23 voltage regulation architecture, providing an adjustable and power-on-reset function, with the output voltage ranging from 3V to 5.5V. The supervisor also provides an adjustable active-low reset output and an active-low pulse-width-modulated low dropout voltage regulator (LDO).

The S-1009C34I-I4T1U is ideal for personal computers, consumer digital audio players and a variety of other consumer electronics. It is often used to supply low voltage power with a reliable reset output for system supervision in mobile platforms such as mobile phones and PDAs. The ultra-compact form factor and the integration of power & reset circuit in one package simplify system design and save critical board space.

The working principle of the S-1009C34I-I4T1U safety system can be summarized as the following:

• An integrated power monitoring signal interacts with the reset circuitry to monitor system power, allowing the reset signal to be driven to its output during device power-up.
• The supervisor\'s reset output is asserted when device power is not detected, as indicated by the internal power monitoring signal, following the device configuration delays.
• The active-low reset output can be tested and adjusted to provide reset thresholds between 3V and 5.5V.
• The LDO output is operational when the regulator is enabled and the LDO is operating, indicated by an active-low open-collector output.
• The S-1009C34I-I4T1U also provides a small reset pulse (<10ms) that can be enabled to allow time for the active-low pulse width-modulated LDO output to come up and hold the system from resetting.

The S-1009C34I-I4T1U provides a number of features not found in other PMIC supervisory devices. It is an ultra-small device, needing only a tiny space on the board, and provides adjustable active-low reset output, making it suitable for a variety of applications requiring system stability and safety. Additionally, the integrated LDO allows low voltage power sources to be used, making it an ideal choice for low power applications. Furthermore, a Pb-free lead finish is available to meet RoHS requirements.

In conclusion, the S-1009C34I-I4T1U PMIC supervisor is ideal for a wide range of applications due to its small size and low power consumption, as well as its wide range of features. It provides a reliable source for system reset and holds, as well as providing adjustable voltage outputs for low voltage power to work reliably.
