| Voltage - threshold | 2.93V |
| Number of voltages monitored | 1 |
| Operating temperature | -55°C~125°C(TA) |
| Reset | Active Low |
| Output | Push-Pull, Totem Pole |

| Case | 8-TSSOP, 8-MSOP (0.118\", 3.00mm Width) |
The push-pull, totem-pole output drives the reset line without an external pull-up resistor, which saves a component on the BOM in dense layouts.
Housed in an 8-VSSOP (3.00 mm width, 0.118-inch pitch), the part fits on a two-layer board with minimal fan-out.
The reset threshold is 2.93 V. The part monitors a single voltage rail and asserts an active-low reset when the rail falls below that level.
The reset timeout is 60 ms minimum. After the monitored rail recovers above the threshold, the output stays low for at least 60 ms before releasing.
The alternate case style is 8-TSSOP or 8-MSOP.
