SC33001A/SC33001AH

3A Low V_INUltra-Low Rdson Load Switch

POWER MANAGEMENT

Features

Description

The SC3300ꢀA/AH are a family of an ultra-low Rdson load

switch optimized for use in battery powered applications.

This family of devices support up to 3A continuous output

current. Sophisticated integrated circuitry maximizes

Vgs of the power NMOS to minimize Rdson resistance

over a wide range of operating conditions.



Input voltage range — ꢀ.7V to 5.5V

3A continuous output current

Ultra-Low Rdson — 9mΩ

Constant Rdson over wide V_INrange

Device Options

• SC3300ꢀA — Slow turn on slew and with auto-

matic output discharge

The device provides a controlled soft-start to limit inrush

current. SC3300ꢀA features an automatic discharge

circuit which discharges the output when the SC3300ꢀA is

disabled. SC3300ꢀAH does not include the automatic

output discharge circuitry.

• SC3300ꢀAH — Slow turn on slew with no

output discharge circuit

Typical current limit 6A



Minimum current limit 3A

Typical foldback current limit 2A

Over temperature protection

Low shutdown current

SC3300ꢀA/AH family has integrated current limit and over

temperature to prevent the device from failure when

down stream circuitry is at low impedance fault

conditions.

Low quiescent current



Package: CSP — 0.9mm x ꢀ.4mm , 0.5mm Pitch

The SC3300ꢀA/AH are oﬀered in an ultra small 6-bump

0.9mm x ꢀ.4mm Chip Scale Package (CSP) which enables

very small board area implementations. The SC3300ꢀA/

SC3300ꢀAH has an operating temperature range of -40⁰C

to +85⁰C.

Applications



Battery powered equipment

Smart Phones/Tablet PCs

Consumer electronics

STB/Audio/Video

Industrial/Network equipment

Other Portable Devices

Typical Application Circuit
