TLV3201 TLV3202 SBOS561A – MARCH 2012 – REVISED JUNE 2012 www.ti.com APPLICATION INFORMATION The TLV3201 and TLV3202 are single- and dual-supply (respectively), push-pull comparators featuring 40 ns of propagation delay on only 40 µA of supply current.
PAGE 11
TLV3201 TLV3202 www.ti.com SBOS561A – MARCH 2012 – REVISED JUNE 2012 EXTERNAL HYSTERESIS The TLV3201 and TLV3202 have a hysteresis transfer curve (shown in Figure 27) that is a function of the following three components: • VTH: the actual set voltage or threshold trip voltage • VOS: the internal offset voltage between VIN+ and VIN–. This voltage is added to VTH to form the actual trip point at which the comparator must respond in order to change output states.
PAGE 12
TLV3201 TLV3202 SBOS561A – MARCH 2012 – REVISED JUNE 2012 www.ti.com Inverting Comparator With Hysteresis The inverting comparator with hysteresis requires a three-resistor network that is referenced to the comparator supply voltage (VCC), as shown in Figure 28. When VIN at the inverting input is less than VA, the output voltage is high (for simplicity assume VO switches as high as VCC). The three network resistors can be represented as R1 || R3 in series with R2.
PAGE 13
TLV3201 TLV3202 www.ti.com SBOS561A – MARCH 2012 – REVISED JUNE 2012 Noninverting Comparator with Hysteresis A noninverting comparator with hysteresis requires a two-resistor network, as shown in Figure 29, and a voltage reference (VREF) at the inverting input. When VIN is low, the output is also low. For the output to switch from low to high, VIN must rise up to VIN1. VIN1 is calculated by Equation 4: VREF VIN1 = R1 ´ ´ VREF (4) R2 When VIN is high, the output is also high.

TLV3201 TLV3202 SBOS561A – MARCH 2012 – REVISED JUNE 2012 www.ti.com CIRCUIT LAYOUT The TLV3201 and TLV3202 are fast-switching, high-speed comparators and require high-speed layout considerations. For best results, the following layout guidelines should be maintained: 1. Use a printed circuit board (PCB) with a good, unbroken low-inductance ground plane. 2. Place a decoupling capacitor (0.1-μF ceramic, surface-mount capacitor) as close as possible to VCC. 3.

TLV3201 TLV3202 www.ti.com SBOS561A – MARCH 2012 – REVISED JUNE 2012 Figure 31 shows a single-supply current monitor configured as a difference amplifier with a gain of 50. The OPA320 was chosen for this circuit because of its gain bandwidth (20 MHz), which allows higher speed triggering and monitoring of the current across the shunt resistor followed by the fast response of the TLV3201. Figure 31.

TLV3201 TLV3202 SBOS561A – MARCH 2012 – REVISED JUNE 2012 www.ti.com Figure 32 shows the TMP20 and TLV3201 designed as a high-speed temperature switch. The TMP20 is an analog output temperature sensor where output voltage decreases with temperature. The comparator output is tripped when the output reaches a critical trip threshold. Figure 32.
