Product Overview
The TPS2493 is a Texas Instruments high-voltage hotswap controller for Power_Management designs using a PW14, 14-pin package. Its recommended VCC operating range is 9 to 80 V, and the specified junction operating temperature range is -40 to 125 °C. The TPS2493 variant uses retry operation, with a specified fault retry duty cycle of 0.75% typical.
Electrical limits include -0.3 to 100 V absolute maximum voltage ratings for VCC, SENSE, UVEN, OUT, GATE, PG, and FLT pins, and -0.3 to 6 V ratings for PROG, OV, TIMER, VREF, and IMON. The VCC-to-SENSE differential absolute maximum rating is -1.5 to 1.5 V.
Control and protection functions include UVEN and OV thresholds, current limiting with and without power limiting, TIMER source and sink currents, GATE sourcing, sinking, and strong sinking currents, plus PG and FLT status outputs. The IMON output provides load-current monitoring with 48 V/V typical gain, 2.8 V typical maximum output voltage, and 0.3% linearity for the stated condition.
