APPLICATION INFORMATION
undervoltage lockout (UVLO)
The TPS2320/TPS2321 includes an undervoltage lockout (UVLO) feature that monitors the voltage present on
the VREG pin. This feature will disable both external MOSFETs if the voltage on VREG drops below 2.78 V
(nominal) and will re-enable normal operation when it rises above 2.85 V (nominal). Since VREG is fed from
IN1 through a low-dropout voltage regulator, the voltage on VREG will track the voltage on IN1 within 50 mV.
While the undervoltage lockout is engaged, both GATE1 and GATE2 are held low by internal PMOS pulldown
transistors, ensuring that the external MOSFET transistors remain off at all times, even if all power supplies have
fallen to 0 V.
single-channel operation
Some applications may require only a single external MOS transistor. Such applications should use GATE1 and
the associated circuitry (IN1, ISENSE1, ISET1, DISCH1). The IN2 pin should be grounded to disable the
circuitry associated with the GATE2 pin.
power-up control
The TPS2320/TPS2321 includes a 500
μ
s (nominal) startup delay that ensures that internal circuitry has
sufficient time to start before the device begins turning on the external MOSFETs. This delay is triggered only
upon the rapid application of power to the circuit. If the power supply ramps up slowly, the undervoltage lockout
circuitry will provide adequate protection against undervoltage operation.
3-channel hot-swap application
Some applications require hot-swap control of up to three voltage rails, but may not explicitly require the sensing
of the status of the output power on all three of the voltage rails. One such application is device bay, where dv/dt
control of 3.3 V, 5 V, and 12 V is required. By using Channel 2 to drive both the 3.3-V and 5-V power rails and
Channel 1 to drive the 12-V power rail, as is shown below, TPS2320/01 can deliver three different voltages to
three loads while monitoring the status of two of the loads.
