L7585G Full-Feature, Low-Power SLIC and Switch
Electrical Characteristics
In general, minimum and maximum values are testing requirements. However, some parameters may not be
tested in production because they are guaranteed by design and device characterization. Typical values reflect the
design center or nominal value of the parameter; they are for information only and are not a requirement. Minimum
and maximum values apply across the entire temperature range (–40 °C to +85 °C) and entire battery range
(–35 V to –60 V). Unless otherwise specified, typical is defined as 25 °C, V
CCA
= +5.0 V, V
CCD
= +5.0 V,
V
SP
= +10 V, V
BAT
= –48 V. Positive currents flow into the device.
* Not to exceed 26 grams of water per kilogram of dry air.
This parameter is not tested in production; it is guaranteed by design and device characterization.
1. The ringing source may be either of the following:
a) The ringing source consists of the ac and dc voltages added together (battery-backed ringing); the ringing return is ground. In this case,
bit B3 will always be a 1 when ringing is applied.
b) The ringing source consists of only the ac voltage (earth-backed ringing); the ringing return is the dc voltage. In this case, bit B3 will
always be a 0 when ringing is applied.
2. NDET must also indicate ring trip when the ac ringing voltage is absent (<5 Vrms) from the ringing source.
3. Pretrip ringing must not be tripped by a 10 k
resistor in parallel with an 8 μF capacitor applied across tip and ring.
