Littelfuse has expanded its protection IC product line to include five load switch ICs that deliver power savings in a small package.

Littelfuse, Inc. has announced the release of five load switch ICs in its protection IC product line. Featuring a small form factor and high efficiency, they target IoT, mobile, handheld devices, SSD storage, building automation, consumer electronics and wearable electronics applications.

The ICs combine low-power consumption and power savings and easy-to-power on/off controls. The small chip-scale form factor not only saves space, but also integrates functions such as slew rate control, true reverse, current blocking and quick output discharging. They support the industry’s lowest quiescent current (IQ), low RON and shutdown current (ISD) to reduce parasitic leakage current, improve system efficiency and increase overall battery lifetime, Littelfuse said.

The new load switch ICs include the following series: LQ05021QCS4 (5 V, 2 A, ultra-low power consumption with slew rate control), LQ05021RCS4 (5 V, 2 A, ultra-low consumption with true reverse current blocking), LQ05022QCS4 (5 V, 2 A, ultra-low consumption with slew rate control), LQ05041QCS6 (5 V, 4 A, ultra-low power consumption with slew rate control) and LQ05041RCS6 (5 V, 4 A ultra-low power consumption with true reverse current blocking).

The load switch ICs are currently available in tape and reel in quantities of 4,000 in the following series: LQ05021QCS4, LQ05021RCS4 and LQ05022QCS4) or in quantities of 3,000 for the LQ05041QCS6 and LQ05041RCS6. Sample requests can be ordered through Littelfuse’s authorized distributors.

The devices are available in a small, chip-scale package with four bumps in a 0.77 × 0.77 × 0.46 mm package size on a 0.4-mm pitch, four bumps in a 0.97 × 0.97 × 0.55 mm die size on a 0.4-mm pitch or six bumps in a 0.97 × 1.47 × 0.55 mm package size on a 0.5-mm pitch.
