Pin Description

Name

Function

V+

Power supply positive voltage input.

GND

Power supply ground input.

CAP

−

Connect this pin to the negative terminal of the charge-pump capacitor.

Shutdown control pin, tie this pin to ground in normal operation.

VOUT

Positive voltage output.

CAP+

Connect this pin to the positive terminal of the charge-pump capacitor.

These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam

during storage or handling to prevent electrostatic damage to the MOS gates.

(1)

Absolute maximum ratings indicate limits beyond which damage to the device may occur. Electrical specifications do not apply when

operating the device beyond its rated operating conditions.

(2)

If Military/Aerospace specified devices are required, please contact the TI Sales Office/ Distributors for availability and specifications.

(3)

VOUT may be shorted to GND for one second without damage. However, shorting VOUT to V+ may damage the device and should be

avoided. Also, for temperatures above 85°C, OUT must not be shorted to GND or V+, or device may be damaged.

(4)

The maximum allowable power dissipation is calculated by using PDMax = (TJMax − TA)/θJA, where TJMax is the maximum junction

temperature, TA is the ambient temperature, and θJA is the junction-to-ambient thermal resistance of the specified package.

Junction Temperature Range

−40° to 100°C

Ambient Temperature Range

−40° to 85°C

Storage Temperature Range

−65°C to 150°C

Lead Temp. (Soldering, 10 seconds)

240°C

Human Body Model

2kV

ESD Rating (2)

Machine Model

200V

(1)

The maximum allowable power dissipation is calculated by using PDMax = (TJMax − TA)/θJA, where TJMax is the maximum junction

temperature, TA is the ambient temperature, and θJA is the junction-to-ambient thermal resistance of the specified package.

(2)

The human body model is a 100pF capacitor discharged through a 1.5k

Ω resistor into each pin. The machine model is a 200pF

capacitor discharged directly into each pin.
