Description

The TSX339 is a micropower CMOS dual voltage comparator which exhibits a very low current consumption of 5 µA typical per comparator. This device was designed as the improvement of the TS339: it shows a lower current consumption, a better input offset voltage, and an enhanced ESD tolerance. The TSX339 is fully specified over a wide temperature range and is proposed in automotive grade for the TSSOP14 package. It is fully compatible with TS339 CMOS comparator and is available with similar packages. The new tiny package, QFN16 3x3, is also proposed for the TSX339 thus allowing even more integration on applications.

6 Application information

6.1 Input voltages

The output state is guaranteed as long as one input remains within the common mode input voltage range (defined in the operating conditions table), and the other input remains between -0.3 V and 16 V (meaning that one input can be driven above VCC+). If one input voltage is beyond the range 0 V to 16 V, this input of the comparator should be protected according to Figure 17. If the input is lower than Vcc-, a significant current may go through the ESD diode. To protect the circuit, this current must be limited to 10 mA by using the Rg+ or Rg- resistors. If the input is bigger than 16 V, it has to be voltage limited. This is achieved using the D- or D+ additional, external diodes. To protect these diodes, the current is limited using the Rg resistor. D- and D+ diodes can be connected to another power supply with a maximum value of 16 V. The device is designed to prevent phase reversal. Figure 17: Additional, external, protection schematic

6.2 For unused channel

An unused comparator has to be configured to avoid unexpected additional consumption. A simple solution is to connect the input to the power supply pins as shown in Figure 18. This keeps the circuit in a stable state. Figure 18: Input configuration for unused channel

6.3 Bypass capacitor

To maintain proper coupling of the power supply, it is strongly recommended to place a 0.1 μF capacitor as close as possible to the supply pins.
