1 Description

level (above VTH+ or below VTH- ) and the state of EN and INH inputs. miniature flip chip 6-bump package. Figure 1. Logic diagram

2 Operation

level, VCC (see Table 2 or Figure 11 for more details).

2.1 Output, OUT

output is connected to ground GND. The output is current limited (see Table 5).

2.2 Enable input, EN

which enters a standby mode with very low current consumption (see Table 5).

2.3 Inhibit input, INH

A logic high on the inhibit input disconnects the output from VIN. Table 2. Truth table

  1. Once the device is disabled by EN input, the V CC must be above VTH+ to reconnect output to VIN.

3 Typical operating characteristics

Figure 5. Supply current vs. supply voltage, V EN = 4 V Figure 6. Supply current vs. temperature, V EN = 4 V

4 Maximum ratings

Program and other relevant quality documents. Table 3. Absolute maximum ratings

5 DC and AC characteristics

Figure 11. Waveforms VCC then there will be no VIN. Table 4. Operating and AC measurement conditions

Table 5. DC and AC characteristics

  1. Valid for ambient operating temperature: T A = –30°C to +85°C; VCC = 2.7 V to 5.5 V (except where noted).
  2. For V CC below VTH-, the output remains low down to VCC = 1 V. Below VCC = 1 V the voltage VIN must be less than

VOUT-OL (max.) to guarantee output low voltage less than 0.3 V.
