The TPS389x family also has a logic • Low Quiescent Current: 6 µA (Typical) enable pin (ENABLE or ENABLE) to power on and off • External Enable Input the output. With the TPS3895, for example, when the input voltage pin (SENSE) rises above the threshold, • Open-Drain (Rated at 18 V) and Push-Pull Output and the ENABLE pin is high, then the output pin Options (SENSE_OUT) goes high after the capacitor- • Temperature Range: –40°C to 125°C adjustable delay time. When SENSE falls below the • Pin-for-Pin Compatible With MAX6895/6/7/8 threshold or ENABLE is low, then SENSE_OUT goes low. For truth tables, see Table 1 and Table 2. 2 Applications For TPS389xA versions, both SENSE and ENABLE • DSPs, Microcontrollers, and Microprocessors have a capacitor-adjustable delay. The output asserts after this capacitor-adjustable delay when both • Notebook and Desktop Computers SENSE and ENABLE inputs are good. The • PDAs and Handheld Products TPS389xP devices have a small, 0.2-µs propagation • Portable and Battery-Powered Products delay from when the enable pin asserts to when the • FPGAs and ASICs output pin asserts, provided SENSE is above the threshold. All devices operate from 1.7 V to 6.5 V and have a typical quiescent current of 6 µA with an open-drain output rated at 18 V. The TPS389x is available in an ultra-small USON package and is fully specified over the temperature range of TJ = –40°C to 125°C.
