Product details
Overview
CY8C4147LCE-HV413T from Infineon is a 32-bit Arm® Cortex®-M0+ MCU optimized for lead-acid battery monitoring, featuring dual 16–20+ bit ΔΣ ADCs (current/voltage/temperature), integrated LIN transceiver compliant with LIN 2.2A/SAE J2602/ISO 17987, and high-voltage operation up to 42 V. It includes 128 KB flash with ECC, 8 KB SRAM with ECC, and supports ASIL B hardware metrics per ISO 26262.
For engineers reviewing the CY8C4147LCE-HV413T datasheet, CY8C4147LCE-HV413T pinout, CY8C4147LCE-HV413T application, or CY8C4147LCE-HV413T equivalent, key selection criteria include HV battery input tolerance (42 V), dual precision ΔΣ ADC channel architecture, LIN 2.2A protocol compliance, ASIL B safety certification, and 32-QFN wettable flanks package compatibility with automotive PCB assembly requirements.
Technical Context
The device integrates a dedicated high-voltage subsystem with on-die voltage dividers enabling direct 12 V/24 V battery sensing, plus two independent ΔΣ ADCs-one with automatic gain control for current measurement and one with HV input scaling for battery voltage. Its analog diagnostics include redundant measurement paths and backup reference voltage monitoring.
Functional safety is implemented via hardware SECDED ECC on all safety-critical memories (flash/SRAM), MPU-enforced memory isolation, windowed WDT with challenge-response, and supply monitors detecting overvoltage/brownout on both 3.3 V and 1.8 V rails-meeting ISO 26262 hardware architectural metrics for ASIL B.

Equivalent & Alternatives
The following parts are listed as comparable options for similar battery monitoring controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX17853 | Dedicated 12-cell battery monitor IC with daisy-chain interface; no MCU core or LIN transceiver. | Requires external host MCU and LIN gateway; suited for multi-cell lithium systems, not lead-acid. | Select when monitoring >4 cells or needing cell-level balancing - not a drop-in replacement for single-battery HVPA use cases. |
| STM32G474RET6 | General-purpose Cortex-M4 MCU with 12-bit ADC and no integrated LIN PHY or HV input capability. | Needs external LIN transceiver, HV voltage divider, and safety software certification effort. | Select when flexibility in peripheral configuration outweighs integrated safety and analog features - increases BOM and validation scope. |
Compared with MAX17853 and STM32G474RET6, CY8C4147LCE-HV413T uniquely combines HV battery interface, dual high-resolution ΔΣ ADCs, certified LIN PHY, and ISO 26262 ASIL B hardware metrics in a single 32-QFN package - minimizing system complexity for lead-acid battery monitoring.

FAQ
Does CY8C4147LCE-HV413T support LIN 2.2A and SAE J2602 simultaneously?
Yes. The integrated LIN block complies with LIN 2.2A, 2.1, 2.0, 1.3, SAE J2602, and ISO 17987 in a single hardware implementation. Protocol selection is configured in firmware, and all versions share the same physical layer - enabling seamless interoperability with diverse vehicle ECUs without hardware changes.
What is the maximum measurable battery voltage using the integrated HV input divider?
The internal HV voltage divider scales VBAT (up to 42 V) to a safe range for the ΔΣ ADC input. With full-scale ADC reference of 1.2 V and 20-bit resolution, the effective measurement range is 0–42 V with ±0.1% typical linearity error and 12-bit effective resolution after digital filtering - sufficient for ±0.5 V SOC accuracy in 12 V systems.
How is functional safety implemented without external watchdog or memory controllers?
Functional safety is achieved through on-die hardware: SECDED ECC on flash/SRAM, MPU-enforced memory partitioning, windowed WDT with challenge-response handshake, and independent supply monitors for 3.3 V and 1.8 V rails. These features satisfy ISO 26262 ASIL B hardware metrics without requiring external safety components.
Can the dual ΔΣ ADCs operate concurrently during low-power modes?
Yes. Both ΔΣ ADCs can acquire data in DeepSleep mode using the 32 kHz PILO clock, with results stored in SRAM and wake-up triggered by threshold violation or timer expiration. This enables continuous battery monitoring at <10 µA total system current - critical for always-on vehicle battery health tracking.
