Product details
Overview
2ED4820EMXUMA2 from Infineon Technologies is a smart high-side MOSFET gate driver IC for 48 V automotive battery protection applications, featuring two independent 1 A pull-down / 0.3 A pull-up gate outputs, SPI-based configuration and diagnostics, and integrated charge pump for gate voltage generation. It supports back-to-back MOSFET topologies (common source and common drain) and includes bidirectional analog current sense with configurable gain.
For engineers reviewing the 2ED4820EMXUMA2 datasheet, 2ED4820EMXUMA2 pinout, 2ED4820EMXUMA2 application, or 2ED4820EMXUMA2 equivalent, key selection criteria include its AEC-Q100 Grade 1 qualification, <5 µA sleep-mode supply current, gate undervoltage lock-out, drain-source overvoltage detection, and safe state mode activation via dedicated SAFESTATEN pin.
Technical Context
The device implements a one-stage integrated charge pump with external tank and pump capacitors to generate gate drive voltage (VCP) for high-side MOSFETs in 48 V systems. Its dual-channel architecture enables pre-charge control in highly capacitive loads using one channel while the other handles main switching.
SPI interface provides full register-level access for real-time configuration of overcurrent thresholds, blank/filter times, gain settings for the current sense amplifier, and fault response modes (latching vs. non-latching). Protection logic includes ground loss detection, open-load monitoring via source voltage sensing in OFF state, and temperature warning/shutdown.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 20–70 V - Enables direct connection to 48 V battery rails with margin for transients and ripple. |
| Gate Drive Output | 1 A sink / 0.3 A source per channel - Supports parallel MOSFET driving to reduce conduction losses in high-current switches. |
| Sleep Current | <5 µA IBAT_Q - Minimizes quiescent power draw during vehicle standby or ignition-off states. |
| Current Sense Interface | Bidirectional, configurable gain (via external resistors) - Allows flexible placement (high-side or low-side shunt) and scaling for precise load current monitoring. |
| Protection Features | VDS overvoltage, VGS undervoltage lock-out, thermal warning/shutdown, ground loss detection - Prevents MOSFET destruction under fault conditions without MCU intervention. |
| Interface | 16-bit SPI with daisy-chain capability - Enables multi-device control and diagnostics with minimal MCU GPIO usage. |
| AEC-Q100 Qualification | Grade 1 (−40 °C to +125 °C ambient) - Validated for under-hood automotive environments including battery disconnect units and DC/DC input stages. |
Pinout & Package
Package: PG-TSDSO-24 (24-pin thermally enhanced thin shrink small outline package with exposed pad).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VBAT | Main high-voltage supply input | Connects directly to 48 V battery rail; powers internal regulators and charge pump stage. |
| VDD | Logic supply input | Accepts 3.3 V or 5 V MCU-compatible supply for digital core and SPI interface. |
| CPGND / AGND / GND | Ground reference terminals | Separate power (CPGND), analog (AGND), and digital (GND) grounds minimize noise coupling into current sense and SPI paths. |
| SA / SB / ISP / ISN / CSO | Analog current sense inputs/outputs | Support bidirectional shunt monitoring; SA/SB differential pair, ISP/ISN for high-/low-side configurations, CSO for buffered output to MCU ADC. |
| GA / GB | Gate drive outputs | Independent high-side drivers with 1 A sink / 0.3 A source capability; support pre-charge and main switch sequencing. |
| SCLK / MOSI / MISO / CSN | SPI interface signals | Full-duplex 16-bit SPI with chip select; supports daisy-chaining up to 4 devices on single bus. |
| INTERRUPT | Fault notification output | Open-drain active-low signal alerts MCU of any latching/non-latching fault event; status registers identify root cause. |
| ENABLE | Device enable input | Active-high logic input enabling normal operation; tied high or controlled by MCU for system-level power sequencing. |
| SAFESTATEN | Safe state activation pin | Direct hardware override forcing both GA/GB outputs OFF regardless of SPI state - critical for fail-safe battery disconnection. |
| VCP / CPH / CPL | Charge pump terminals | VCP = pumped gate drive voltage output; CPH/CPL connect external pump capacitor (CPH) and tank capacitor (CPL) for charge transfer. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent high-side drivers | Enables split-function operation: one channel for pre-charge of capacitive loads (e.g., DC/DC input filter), second for main power path switching. |
| Configurable overcurrent protection | Adjustable trip threshold and blank time via SPI registers - avoids false triggering during inrush while ensuring fast response to short circuits. |
| Integrated charge pump with external caps | Eliminates need for external high-voltage bias supply; supports >100 V VDS blocking capability with standard 40–60 V MOSFETs. |
| Open-load detection | Monitors MOSFET source voltage vs. ground in OFF state - detects broken connections or disconnected loads before enabling switch-on. |
| Ground loss detection | Identifies loss of GND reference at CPGND/AGND/GND pins - prevents unsafe operation due to floating ground or PCB trace failure. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-side gate driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor NCD57001DR2G | Single-channel, 4 A peak sink / 2 A peak source; no integrated charge pump - requires external bootstrap or isolated supply. | Lacks SPI configurability, current sense interface, and AEC-Q100 Grade 1 rating; suited for cost-sensitive non-automotive industrial use. | Select when higher peak drive strength is needed but diagnostic depth and automotive qualification are not required. |
| Texas Instruments UCC27611DR | Single-channel, 10 A peak sink / 5 A peak source; no protection features, no current sense, no charge pump - pure gate driver. | Requires companion protection IC and external high-side bias; intended for high-frequency SMPS, not battery protection. | Select only for ultra-fast switching (>1 MHz) where minimal propagation delay (<15 ns) outweighs integration needs. |
Compared with NCD57001DR2G and UCC27611DR, the 2ED4820EMXUMA2 delivers system-level integration - combining gate driving, protection, diagnostics, and configuration in one AEC-Q100 qualified package - reducing BOM count, PCB area, and validation effort for 48 V automotive power switches.

FAQ
What is the maximum allowable VDS for MOSFETs driven by the 2ED4820EMXUMA2?
The device supports MOSFETs with up to 100 V drain-source blocking capability, enabled by its integrated charge pump generating VCP ≥ 18 V. This ensures sufficient gate overdrive for standard 60 V and 75 V automotive MOSFETs under worst-case VBAT transients (e.g., load dump up to 65 V).
How does the 2ED4820EMXUMA2 handle ground loss detection?
It continuously monitors voltage differences between CPGND, AGND, and GND pins using internal comparators. If any ground reference deviates beyond ±0.5 V relative to others, a latching fault is triggered and reported via INTERRUPT pin and status register bit GND_LOSS_FLAG, forcing safe state activation.
Can the current sense amplifier be used for both high-side and low-side shunt configurations?
Yes - the CSA supports bidirectional measurement with configurable gain via external resistor networks on ISP/ISN pins. High-side sensing uses SA/SB differential inputs; low-side sensing routes shunt voltage to ISP/ISN, with CSO providing buffered output to MCU ADC for software-based protection algorithms.
Is daisy-chaining supported across multiple 2ED4820EMXUMA2 devices?
Yes - the SPI interface supports daisy-chain topology with up to four devices on a single bus. MISO of one device connects to MOSI of the next, while SCLK and CSN remain shared; each device responds to its unique 4-bit address in the 16-bit command frame.
