lated output voltage as low as 1.2 V. The watchdog func-
tion monitors software cycle time and execution. If soft-
ware clears the watchdog too quickly (incorrect cycle
time) or too slowly (incorrect execution) it will cause the
system to be reset. The system enable output prevents
critical control functions being activated until software
has successfully cleared the watchdog three times. Such
a security could be used to prevent motor controls being
energized on repeated resets of a faulty system.

Description
The A6130 offers a high level of integration by combining
voltage regulation, voltage monitoring and software mon-
itoring in an 8 lead package. The voltage regulator has a
low dropout voltage (typ. 380 mV at 100 mA) and a low
quiescent current (155 µA). The quiescent current in-
creases only slightly in dropout prolonging battery life.
Built-in protection includes a positive transient absorber
for up to 60 V (load dump) and the ability to survive an un-
regulated input voltage of -20 V (reverse battery). The in-
put may be connected to ground or a reverse voltage
without reverse current flow from the output to the input. A
comparator monitors the voltage applied at the VIN input
comparing it with an internal 1.17 V reference. The
power-on reset function is initialized after VIN reaches 1.17
V and takes the reset output inactive after TPOR depending
of external resistance. The reset output goes active low
when the VIN voltage is less than 1.17 V. The RES and EN
outputs are guaranteed to be in a correct state for a regu-

Stresses above these listed maximum ratings may cause
permanent damage to the device. Exposure beyond
specified operating conditions may affect device reliabil-
ity or cause malfunction.
Handling Procedures
This device has built-in protection against high static volt-
ages or electric fields; however, anti-static precautions
must be taken as for any other CMOS component. Unless
otherwise specified, proper operation can only occur
when all terminal voltages are kept within the supply volt-
age range. At any time, all inputs must be tied to a de-
fined logic voltage level.

1) The maximum operating temperature is confirmed by
sampling at initial device qualification. In production, all
devices are tested at +85°C.
2) Full operation guaranteed. To achieve the load regulation
specified in Table 3 a 22 µF capacitor or greater is required
on the INPUT, see Fig. 8. The 22 µF must have an effective
resistance £ 5 W and a resonant frequency above 500 kHz.
3) A 10 µF load capacitor and a 100 nF decoupling capacitor
are required on the regulator OUTPUT for stability. The 10 µF
must have an effective series resistance of £ 5 W and a
resonant frequency above 500 kHz.
4) RES must be pulled up externally to VOUTPUT even if it is
unused. (Note: RES and EN are used as inputs by EM test.)
5) The OUTPUT current will not apply for all possible
combinations of input voltage and output current.
Combinations that would require the A6130 to work above
the maximum junction temperature (+85°C) must be
avoided.
6) The thermal resistance specified assumes the package is
soldered to a PCB.

Table 3
1) If INPUT is connected to VSS, no reverse current will flow from the OUTPUT to the INPUT, however the supply current specified
will be sank by the OUTPUT to supply the A6130.
2) The OUTPUT voltage temperature coefficient is defined as the worst case voltage change divided by the total temperature range.
3) Regulation is measured at constant junction temperature using pulse testing with a low duty cycle. Changes in OUTPUT voltage
due to heating effects are covered in the specification for thermal regulation.
4 ) The dropout voltage is defined as the INPUT to OUTPUT differential, measured with the input voltage equal to 5.0 V.
5 )Thermal regulation is defined as the change in OUTPUT voltage at a time T after a change in power dissipation is applied,
excluding load or line regulation effects.
6) The comparator and the voltage regulator have separate voltage references (see Block Diagram Fig. 7).
7) The comparator reference is the power-down reset threshold. The power-on reset threshold equals the comparator reference
voltage plus the comparator hysteresis (see Fig. 4).
