Analog Devices Inc. ADP1196ACBZ-R7

Overview

ADP1196ACBZ-R7 from Analog Devices is a logic-controlled, dual-mode (high-side or low-side) N-channel load switch IC designed for 0 V to 5.5 V input operation with 3 A continuous current capability at 70°C, 10 mΩ typical R_DS(ON), and integrated overtemperature protection. It serves as a precision power-path controller in compact battery-powered systems requiring controlled inrush current and ultralow quiescent power.

For engineers reviewing the ADP1196ACBZ-R7 datasheet, ADP1196ACBZ-R7 pinout, ADP1196ACBZ-R7 application, or ADP1196ACBZ-R7 equivalent, key selection criteria include its 1.0 mm × 1.5 mm WLCSP package, bias-supply-flexible enable interface (VB_EN), constant R_DS(ON) across voltage range, thermal shutdown hysteresis, and 26 µA ground current at VIN ≤ 3.4 V.

Technical Context

The ADP1196ACBZ-R7 integrates an internal charge pump powered by the higher of VIN or VB_EN, enabling robust gate drive for its N-channel MOSFET regardless of input voltage level. Its on-resistance remains stable across 0.1 V to 5.5 V VIN and 1.83 V to 5.5 V VB_EN, eliminating voltage-dependent conduction loss.

It features programmable turn-on delay (~2 ms), slew-rate-controlled output rise time, and dual-stage protection: current limiting at ±4 A and thermal shutdown activation at 125°C with 15°C hysteresis. The VB_EN pin includes built-in hysteresis and VIN-referenced thresholds to reject noise during enable transitions.

FAQ

What is the maximum continuous current rating of the ADP1196ACBZ-R7 under standard operating conditions?

The ADP1196ACBZ-R7 supports 3 A continuous operating current at ambient temperatures up to 70°C. At 85°C, its derated current drops to ±2.22 A due to thermal limitations. This rating assumes proper PCB thermal relief and operation within the specified 0 V to 5.5 V input voltage range. The ADP1196ACBZ-R7 also includes ±4 A current limiting to protect against short-circuit faults.

Can the ADP1196ACBZ-R7 operate with input voltages below 1.8 V, and how does it maintain functionality?

Yes, the ADP1196ACBZ-R7 operates with VIN as low as 0 V and supports full 3 A switching down to VIN = 0.1 V. It achieves this using an internal charge pump powered by the higher of VIN or VB_EN, ensuring sufficient gate drive for the N-channel MOSFET even at ultra-low input voltages. This architecture maintains constant 10 mΩ R_DS(ON) across the entire 0–5.5 V range, unlike conventional load switches that degrade at low VIN.

How does the thermal protection mechanism work in the ADP1196ACBZ-R7, and what happens during sustained overload?

The ADP1196ACBZ-R7 activates thermal shutdown when junction temperature exceeds 125°C, turning off the output until temperature falls below ~110°C (15°C hysteresis). During a persistent short, it enters autonomous thermal cycling: conducting 4 A until shutdown, cooling to 110°C, re-enabling, and repeating. This prevents catastrophic failure while signaling a fault condition. The ADP1196ACBZ-R7 does not latch off permanently, enabling automatic recovery once the fault is removed.

Is the ADP1196ACBZ-R7 compatible with 1.8 V logic systems, and what are the enable threshold specifications?

Yes, the ADP1196ACBZ-R7 is fully compatible with 1.8 V logic. Its VB_EN pin has VIN-referenced thresholds: V_IH = 1.2 V and V_IL = 0.4 V when VIN ≥ 1.8 V, eliminating the need for level shifters or pull-up resistors. The pin also includes built-in hysteresis to reject noise, and a 4 MΩ internal pull-down resistor ensures defined low-state behavior during power-up or floating conditions.

What package type and dimensions does the ADP1196ACBZ-R7 use, and what are its PCB layout implications?

The ADP1196ACBZ-R7 uses a 1.0 mm × 1.5 mm, 6-ball, 0.5 mm pitch Wafer Level Chip Scale Package (WLCSP, CB-6-2), with total footprint <1.5 mm² and height 0.60 mm. Ball A1 is marked for orientation. Its ultrasmall size demands careful stencil design and reflow profiling; thermal vias under the GND ball (C2) are recommended to manage 3 A power dissipation. No external capacitors are required, but 1 µF ceramic input/output caps improve transient response.
