The S-80136BNPF-JGVTFU is a low-voltage dropout (LDO) supervisor designed to improve the power management of portable battery-operated systems. This device family offers a high level of monitoring accuracy and a high (>200 ms) debounce filter time for power-on reset functionality, along with a 2.5 ms enable response time for reset release. It has a low quiescent current of 2 µA and operates over a wide temperature range (-40°C to +125°C).The S-80136BNPF-JGVTFU is suitable for any system where the power supply needs to be regulated to maintain a stable voltage level and reset upon reset release. Its high accuracy and fast response time make it suitable for a wide range of applications, such as cell phones, MP3 players, digital cameras, gaming consoles, and remote control units.The S-80136BNPF-JGVTFU monitors the input voltage at the VIN pin and outputs a reset signal when it falls below the threshold value. This reset signal is then connected to the reset input of the microcontroller, system timer, or other connected device. This allows the device to reset the system when the power supply drops below the programmed level, preventing data corruption or incorrect operation.The S-80136BNPF-JGVTFU is designed with two digital input pins (VINSDN, VINTH) that can be used to program the trip points for the reset and power-on signals. The VINSDN pin is used to set the trip point of the reset signal while the VINTH pin is used to program the trip point of the power-on signal.The S-80136BNPF-JGVTFU also features hysteresis on the device’s reset signal. This hysteresis allows the reset signal to remain asserted until the VIN pin rises above a threshold level, usually 1V beyond the reset threshold. This ensures that the device will not reset until the power supply is stable enough to provide reliable operation.The S-80136BNPF-JGVTFU also includes a debounce filter time for the reset and power-on signals which helps to prevent noise from inducing a reset. The debounce filter time can be programmed using the VINSDN and VINTH pins, and can range from 1 ms to 200 ms. This filter time can also be enabled or disabled by asserting the OE pin on the device.The S-80136BNPF-JGVTFU also has an enable pin (EN) which allows the user to manually assert the reset signal. This can be useful in some applications, such as when debugging a system or during power-up and power-down cycles, by allowing the user to reset the system without having to manually cycle the power supply.In summary, the S-80136BNPF-JGVTFU is a very versatile and reliable device which can be used to precisely regulate the power supply in a variety of different systems. Its fast response time and hysteresis features allow it to provide a robust and reliable reset signal, while its low quiescent current makes it an ideal choice for portable battery-operated applications. Furthermore, its programmable trip points and debounce filter time make it highly customizable for a wide variety of different system designs.
