General Description

The MIC2505, MIC2505-1, MIC2505-2, and MIC2506 are single and dual integrated high-side power switches that consist of TTL compatible control/enable inputs, a charge pump, and protected N-channel MOSFETs. The MIC2505/6 family can be used instead of separate high-side drivers and MOSFETs in many low-voltage applications.

Features

• Low MOSFET on resistance to 2.7V

30mΩ typical at 5V (MIC2505-series)

35mΩ typical at 3.3V (MIC2505-series)

75mΩ typical at 5V (each MIC2506 output)

80mΩ typical at 3.3V (each MIC2506 output)

• 2.7V to 7.5V input

• 110µA typical on-state supply current

• 1µA typical off-state supply current

• Output can be forced higher than input (off-state)
