SLVSFE3B November 2020 – May 2021 TPS2661
The TPS2661x devices are powered from an external +Vs/-Vs supply. This ensures that the TPS2661x does not draw any current from the IN/OUT pins which carry current information. TPS26610 allows current conduction from IN to OUT pins when +Vs/-Vs supplies are not present. TPS26611 and TPS26612 devices need +Vs/-Vs or +Vs/GND for operation.
For systems requiring positive and negative voltage on IN and OUT pins of TPS2661x, use bipolar supplies (+Vs and -Vs) with TPS2661x. Connect positive supply rail to +Vs and negative supply rail to -Vs pins. The device supports dual supplies from as low as ±2.25 V up to ±20 V.
For systems requiring only positive voltage on IN and OUT pins of TPS2661x, use unipolar supply (+Vs and GND) with TPS2661x.Connect positive supply rail to +Vs and -Vs pin should be connected to GND of device . When powered from single supplies, TPS26610 and TPS26611 devices can be powered from +3 V up to +30 V and TPS26612 can be powered from +4 V up to +30 V.
The device turns-on the internal FETs
with a delay time of tON_dly after powering up of +Vs supply and turns
off the internal FET with a delay time of tOFF_dly after powering down of
+Vs supply. See Timing Requirements in Specifications for tON_dly and
