Diodes Incorporated ZXMS82090S14P-13

Overview

ZXMS82090S14P from Diodes Incorporated is a dual-channel high-side power switch in SO-14EP package, integrating n-channel vertical MOSFETs with charge-pump gate drive, temperature/current sensing, and diagnostic feedback. It operates from 5V–28V supply, delivers 3.5A nominal load current per channel, features 180mΩ R_DS(ON) at +150°C, and supports 3.3V/5V logic-level inputs for automotive and industrial load switching.

For engineers reviewing the ZXMS82090S14P datasheet, ZXMS82090S14P pinout, ZXMS82090S14P application, or ZXMS82090S14P equivalent, key selection criteria include dual-channel diagnostic current-sense accuracy (K_ILIS = 1500), open-load detection in ON/OFF states, defined fault signaling under overload/overtemperature/short-circuit, and SO-14EP thermal performance (R_θJS = 4°C/W).

Technical Context

The device implements two independent high-side switches with monolithic n-channel vertical power MOSFETs, each driven by an internal charge-pump circuit enabling full enhancement from 3.3V/5V logic without external boost components. Gate drive is synchronized to maintain controlled dV/dt (0.1–0.5 V/µs) for EMC compliance.

Diagnostic functionality uses a single IS pin with multiplexed analog current output: proportional to selected channel's load current (I_L/K_ILIS) when enabled, or fixed I_IS(FAULT) during overload, overtemperature, short-circuit, or open-load (OFF-state). Fault detection relies on dynamic ∆T_J(SW) cycling and absolute T_J(SC) shutdown at +150°C to +200°C.

FAQ

What is the maximum continuous load current per channel at +105°C ambient?

The ZXMS82090S14P delivers 3.5A nominal load current per channel at +85°C ambient with appropriate PCB copper area (6 cm² 2oz). At +105°C ambient, derating applies: based on R_θJA = 47°C/W and T_J(MAX) = +150°C, maximum continuous current reduces to approximately 2.2A per channel with standard FR4 mounting.

Can the IS pin be connected directly to a microcontroller ADC input?

No - the IS pin outputs current (not voltage), so it requires an external sense resistor (e.g., 1kΩ) to convert I_IS to measurable voltage. For K_ILIS = 1500, 3.5A load yields 2.33mA → 2.33V across 1kΩ, compatible with most 3.3V ADCs. A low-pass RC filter (e.g., 10kΩ/10nF) is recommended to suppress switching noise.

Does the device support parallel operation of both channels on a single load?

No - the datasheet explicitly advises against connecting both channels in parallel due to lack of synchronization during overtemperature cycling and independent fault handling. Each channel must drive separate loads; shared IS diagnostics require DSEL toggling, not concurrent monitoring.

How does the ZXMS82090S14P handle reverse battery conditions?

During reverse battery, the internal body diode conducts, limiting reverse current by load resistance. The device shuts down all functions; external 4.7kΩ resistors on INx, DEN, and DSEL pins are mandatory to limit reverse current into logic inputs and prevent damage. No active protection is provided in this mode.
