The LMV393-N and LMV339-N are low-voltage (2.7 to 5 V) versions of the dual and quad comparators, LM393/339, which are specified at 5 to 30 V. The LMV331-N is the single version, which is available in space-saving, 5-pin SC70 and 5-pin SOT23 packages. The 5-pin SC70 is approximately half the size of the 5-pin SOT23.

The LMV393-N is available in 8-pin SOIC and VSSOP packages. The LMV339-N is available in 14-pin SOIC and TSSOP packages.

The LMV331-N/393-N/339-N is the most cost-effective solution where space, low voltage, low power, and price are the primary specification in circuit design for portable consumer products. They offer specifications that meet or exceed the familiar LM393/339 at a fraction of the supply current.

The chips are built with TI's advanced Submicron Silicon-Gate BiCMOS process. The LMV331-N/393-N/339-N have bipolar input and output stages for improved noise performance.

TIDA-00500 — 用于 PLC 模块且基于电容器的备用电源参考设计

TIDA-00500 作为参考设计,用于在发生电源中断后在短时间内为负载供电。传统上,可编程逻辑控制器 (PLC) 配备了可充电电池源来提供替代电源。这种电池源通常存在充电拓扑复杂、充电时间长、需要定期维护和引发生态危险等缺点。如果在电源中断后需要使 PLC 在短时间内正常工作,那么使用基于电容器的备用电源是一种更简单、更高效的方法,因为相较于基于电池的解决方案,前者的功率密度更高。
