STMicroelectronics TSM114
The TSM114 integrated circuit incorporates all of the sensing circuitry required to regulate and protect a multiple-output power supply (3.3V, 5V, and ±12V) from both over-voltage and under-voltage. The TSM114 also includes all of the necessary functions for housekeeping features, which allow for safe operation under all conditions, as well as very high system integration. This pin goes low upon an under voltage condition.| Part No. | TSM114 |
