8.3.4 Immunity to Input Terminal Voltage Transients

The TPS3700 device is relatively immune to short voltage transient spikes on the input terminals. Sensitivity to

transients depends on both transient duration and amplitude; see the Minimum Pulse Width vs Threshold

Overdrive Voltage curve (Figure 7) in Typical Characteristics.

8.4 Device Functional Modes

8.4.1 Normal Operation (VDD > UVLO)

When the voltage on VDD is greater than 1.8 V for at least 150 µs, the OUTA and OUTB signals correspond to

the voltage on INA+ and INB– as listed in Table 1.

8.4.2 Undervoltage Lockout (V(POR) < VDD < UVLO)

When the voltage on VDD is less than the device UVLO voltage, and greater than the power-on reset voltage,

V(POR), the OUTA and OUTB signals are asserted and high impedance, respectively, regardless of the voltage on

INA+ and INB–.

8.4.3

Power-On Reset (VDD < V(POR))

When the voltage on VDD is lower than the required voltage to internally pull the asserted output to GND (V(POR)),

both outputs are in a high-impedance state.
