Power Management IC (PMIC) - Supervisors are specialized integrated circuits designed to supervise the power supply of electronic systems. Supervisors monitor the various signals in the power supply, ensuring that all levels remain within their intended range. When the monitored level exceeds its range, the supervisor will act to protect the system by cutting off power. One example of a PMIC - Supervisor is the S-1003CB32I-M5T1U.

The S-1003CB32I-M5T1U is a 1.0 ± 0.075 V Supervisory IC. This device is designed to support single cell Li-ion and Li-polymer battery charging and discharge protection, supplying the bias voltage to various system levels. It monitors the battery voltage and can be used in protection circuits, with an over-voltage protection trigger capable of cutting off the supply voltage in case of sudden under-voltage or over-voltage conditions. In addition, this device is a single-cell lithium battery charger that can be used from both USB2.0 or adapter inputs.

The S-1003CB32I-M5T1U is applicable in several areas. It can be most commonly found in portable electronic devices, such as smartphones, tablets, laptops, and wearable fitness monitors. As a battery charging and protection device, it can be used in self-powered vehicles, such as electric scooters, electric bicycles, mopeds, and electric motorcycles. The S-1003CB32I-M5T1U is also applicable in various charging devices, such as car chargers, wall chargers, and AC adapters.

The S-1003CB32I-M5T1U employs an adjustable reset output levels and a dead time to ensure efficient operation. The reset output can be set within a 0.8V-3.63V range, and an adjustable dead time of 0.5~16msec provides noise immunity. It also features an adjustable soft start duration which allows the user to adjust the output voltage rate from 0.02 to 0.2 V/ms. This rate can be adjusted according to the system specifications and helps to minimize abrupt voltage spikes, improving battery lifetime.

The S-1003CB32I-M5T1U is also equipped with a over-voltage protection circuit which reduces the output voltage when the monitored voltage exceeds its range for a certain period of time. This circuit also protects against sudden overvoltage situations, by allowing the supervisor to shut off the supply voltage when overvoltage is reached. In addition, this device is able to detect short circuit conditions and has a thermal protection circuit which shuts off the device in case of overheat.

In addition, the S-1003CB32I-M5T1U supports adjustable input high voltage limiting, which is used to limit the input voltage to a certain level. This feature helps to protect the system against overvoltage conditions, while providing enhanced output performance. Furthermore, this device has an internal pull down resistor which can be used to limit the standby current.

The S-1003CB32I-M5T1U is a 1.0 ± 0.075 V Supervisory IC that is applicable to several fields. This device monitors the battery voltage and can be used for protection circuits. It can be commonly found in portable electronic devices, such as smartphones and wearables, as well as in self-powered vehicles. In addition, this device supports adjustable reset output levels, adjustable soft start duration, over-voltage protection circuit, short circuit detection, and thermal protection. It also features a adjustable input high voltage limiting and an internal pull down resistor to limit the standby current.
