NOTES:
1. For negative voltages on the BATT and IGN IN inputs, current drain is primarily reverse junction leakage, except when DATA IN, CUR
OUT, ENABLE and RESET are directly connected to BATT. (Note 2)
2. For negative voltage DATA IN, CUR OUT, ENABLE and RESET interface to NPN or equivalent on-chip structures; providing a forward
junction for current conduction into the IC. Negative current must be limited by the impedance of the external connection. This is also the
case where these terminals are interconnected to BATT, Normal application does not require the BATT connection, except for DATA IN
where a series diode for reverse current blocking may be used. (see Description text information)
3. Refer to the Electrical Characteristic TABLE for all Self-Limiting values.
4. Dissipation, approximately equals: P

5. Dropout Voltage is V
DO1

) for REG. OUT1 and V
DO2
= (V

) for REG. OUT2
6. Reset Delay Time, t
RST
is the time period that the RESET (Pin 8) is low following the discharge of the CRST capacitor to ground. For test
evaluation, the CRST pin may be discharged repetitively with a transistor switch. The RESET pin switches from low to high when the
CRST pin is charged to approximately 3V. Normal ATE testing measures the source charging current. which is typically 10
μ
A. For any
other value of Capacitor the charge time, t for reset is determined as follows: t
~
308C, where C is in
μ
F and t is in milliseconds.
(i.e. C = 0.47
μ
F, t = 141ms)
