Diodes Incorporated AP2162MPG-13

Overview

AP2162MPG-13 from Diodes Incorporated is a dual-channel, 1.5A current-limited high-side power switch optimized for USB 2.0 hot-swap applications, featuring active-low enable inputs, 115mΩ typical R_DS(ON) (MSOP-8EP), 7ms deglitched open-drain FLG outputs, and integrated thermal/over-current protection. It operates across 2.7V–5.5V input voltage and supports consumer electronics, computing peripherals, and communications equipment requiring robust load switching with fault reporting.

For engineers reviewing the AP2162MPG-13 datasheet, AP2162MPG-13 pinout, AP2162MPG-13 application, or AP2162MPG-13 equivalent, this device delivers precise 1.5A current limiting, reverse current blocking, sub-1µA shutdown current, and UVLO at 1.9V - critical for reliable USB port power management and hot-plug system design.

Technical Context

The AP2162MPG-13 integrates two independent high-side N-channel MOSFET drivers with dedicated current-sense FETs, enabling accurate 1.5A over-current detection without external sense resistors. Each channel features independent EN1/EN2 inputs (active-low) and FLG1/FLG2 open-drain fault flags with 7ms blanking time to suppress false triggers during capacitive inrush.

Its internal UVLO circuit disables output when VIN drops below ~1.9V, ensuring safe turn-off during brown-out or hot-removal events. Thermal shutdown activates at TJ ≈ 140°C with 25°C hysteresis, and the MSOP-8EP package provides θ_JA = 60°C/W for sustained 1.0A continuous load operation under standard PCB layout conditions.

Key Specifications

Pinout & Package

AP2162MPG-13 is housed in an MSOP-8EP (Exposed Pad) package, where the exposed thermal pad must be soldered to a PCB ground plane for optimal thermal performance (θ_JA = 60°C/W). The pad is electrically isolated and serves only thermal conduction - not as a signal ground path.

FAQ

What is the maximum continuous load current per channel for AP2162MPG-13?

The recommended maximum continuous load current per channel is 1.0A, as specified in the datasheet's "Available Options" table. This rating accounts for thermal limits in the MSOP-8EP package at +85°C ambient, assuming proper PCB copper area and thermal vias to the ground plane. Exceeding 1.0A risks triggering thermal shutdown under sustained load.

Can AP2162MPG-13 be used with 3.3V input instead of 5V?

Yes - the AP2162MPG-13 supports input voltages from 2.7V to 5.5V. At VIN = 3.3V, R_DS(ON) increases to 140–180mΩ (typ/max), raising conduction loss, but current limiting remains accurate at 1.5A. UVLO still functions at ~1.9V, ensuring reliable turn-on even with 3.3V rails.

How does the 7ms FLG blanking time improve system reliability?

The 7ms deglitch timeout prevents the FLG output from falsely asserting during normal capacitive inrush events - such as connecting a 68µF USB port load - which can momentarily exceed 1.5A. This eliminates need for external RC filters or firmware debouncing, enabling immediate fault detection only for genuine sustained over-current or thermal faults.

Is the exposed pad on the MSOP-8EP package electrically connected to GND?

No - the exposed pad is thermally conductive but electrically isolated. It must be soldered to a PCB ground plane solely for heat dissipation (θ_JA = 60°C/W), not as a signal return path. Using it as an electrical ground may compromise thermal performance and violate the device's internal isolation design.
