DS21344B-page 1 Features • Tiny SOT-23A Packages • Optimized for Single Supply Operation • Ultra Low Input Bias Current: Less than 100pA • Low Quiescent Current: 4 µA (TC1037), Shutdown Mode: 4 µA, 0.05µA (TC1038), 6 µA (TC1039) • Shutdown Mode (TC1038) • 2.0% Accurate Independent Voltage Reference (TC1039) • Rail-to-Rail Inputs and Outputs • Operation Down to VDD =1.8V Applications • Power Management Circuits • Battery Operated Equipment • Consumer Products Device Selection Table Package Types General Description The TC1037/TC1038/TC1039 are single, low-power comparators designed for low-power applications. These comparators are specifically designed for operation from a single supply. However, operation from dual supplies also is possible, and power supply current is independent of the magnitude of the power supply voltage. The TC1037/TC1038/TC1039 operate from two1.5Valkalinecells downtoVDD = 1.8V. Active supply current is 4 µA for the TC1037/TC1038 and 6µA for the TC1039. Input and output swing of these devices is rail-to-rail. An active low shutdown input, SHDN, is available on the TC1038 and disables the comparator, placing its output in a high-impedance state. The TC1038 draws only 0.05 µA (typical) when the shutdown mode is active. An internally biased 1.20V bandgap reference is included in the TC1039. The reference is accurate to 2.0 percent tolerance. This reference is independent of the comparator in the TC1039. Packaged in a 5-Pin SOT-23A (TC1037) or 6-Pin SOT-23A (TC1038/TC1039), these single comparators are ideal for applications requiring high integration, small size and low power.
