Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are
stress ratings only and operation at these conditions for extended periods may affect device reliability.
This product utilizes CMOS technology with static protection; however proper ESD prevention procedures should be used
when handling this product. Damage can occur when exposed to extremely high static electrical charge

Notes on Electrical Characteristics:
1/ DC-DC converter in high boost mode (nominal VO=10V) can draw current pulses of greater than 1 Amp and is therefore very
sensitive to series resistance. Critical components of this resistance are the inductor DC resistance, the internal resistance of the
battery and the resistance in the connections from the inductor to the battery, from the inductor to the LX pin and from the Vss2 pin
to the battery. In order to function properly under full load at Vdd=2V, the total of the inductor and interconnect resistances should
not exceed 0.3 ohm. The internal battery resistance should be no more than 0.5 ohm and a low ESR capacitor of 10uF or more
should be connected in parallel with the battery to average current draw over the boost converter cycle.
2/ In the Electrical Characteristics Table, wherever a specific VO value is listed under test conditions, the VO is forced externally
with the inductor disconnected and the DC-DC converter is NOT running.
3/ The brown-out threshold voltage is the VO voltage at which the regulator and horn will be disabled. At VO voltages below the
brown-out threshold Vreg will be pulled to Vss.
4/ In normal operation, the regulator will provide high-side current of up to 20mA, but current sinking capability is typically under 1uA.
The overvoltage clamp is intended to limit the voltage at Vreg when it is pulled up by an external source.
5/ The limits shown are 100% tested at 25C only. Test limits are guard-banded based on temperature characterization to guarantee
compliance at temperature extremes.
