TC1041中文资料Linear Building Block . Dual Low Power Comparator and Voltage Reference with Programmable Hysteresis数据手册Microchip规格书

描述 Description

The TC1041 is a mixed-function device combining two comparators and a voltage reference in a single 8-pin package. The inverting inputs of both comparators are internally connected to the reference. This increased integration allows the user to replace two packages, which saves space, lowers supply current, and increases system performance. The TC1041 operates from two 1.5V alkaline cells down to VDD = 1.8V. It requires only 10A typical supply current which significantly extends battery life. The TC1041 provides a simple method for adding user-adjustable hysteresis without feedback or complex external circuitry. Hysteresis is adjusted with a simple resistor divider on the HYST pin. Rail-to-rail inputs and outputs allow operation from low supply voltages with large input and output signal swings. Packaged in an 8-pin SOIC or 8-pin MSOP, the TC1041 is ideal for applications requiring low-power and small package size.
