Product details
Overview
MCP19215T-E/S8 from Microchip Technology is a digitally enhanced dual-channel PWM controller with integrated 8-bit PIC microcontroller core, designed for precision voltage and current regulation in automotive-grade power converters. It supports 4.5V–42V input, delivers two independent peak-current-mode PWM channels with differential current sensing, and integrates 10-bit ADC, I²C, and AUSART-enabling closed-loop battery charging, LED driver, and bidirectional DC-DC applications.
For engineers reviewing the MCP19215T-E/S8 datasheet, MCP19215T-E/S8 pinout, MCP19215T-E/S8 application, or MCP19215T-E/S8 equivalent, key selection considerations include its AEC-Q100 qualification, dual control loops per channel, 31.25 kHz–2.0 MHz programmable switching frequency, integrated 5V LDO, and 32-pin 5×5 mm QFN package with exposed thermal pad.
Technical Context
The MCP19215T-E/S8 implements two fully independent analog PWM control paths, each with dedicated voltage and current error amplifiers (VCOMP/CCOMP), programmable reference DACs, slope compensation, and leading-edge blanking (0/50/100/200 ns). Its digital subsystem includes an 8 MHz factory-calibrated oscillator, 8192-word Flash, 336-byte RAM, and interrupt-capable peripherals including Timer0/1/2, I²C, and AUSART.
Unlike the MCP19214, the MCP19215T-E/S8 adds full AUSART (TX/RX/CK/DT) and two extra ADC channels (AN4, AN7), plus dual CCD modules (CCD1/CCD2) on GPA6 and GPB7-enabling synchronous communication, enhanced timing capture, and flexible firmware-based protection sequencing in high-reliability power systems.

Equivalent & Alternatives
The following parts are listed as comparable options for similar digitally enhanced dual-channel PWM controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP19214T-E/S8 | 28-pin QFN; lacks AUSART, AN4/AN7, GPB1/GPB6/GPB7; no TX/RX/CK/DT or CCD2 functionality. | Suitable only for simpler single-protocol or non-communication applications; cannot support firmware updates or host telemetry. | Select MCP19214T-E/S8 only when AUSART and extra ADC/capture features are unnecessary and PCB space is constrained. |
| UCC28950PW | Standalone phase-shifted PWM controller (no MCU, no ADC, no serial interface); 4-channel gate drive; no programmable protection. | Requires external MCU for telemetry and adaptive control; limited to fixed-function isolated topologies (LLC, PSFB). | Choose UCC28950PW for high-frequency resonant converters where deterministic analog timing outweighs firmware flexibility. |
Compared with MCP19214T-E/S8, the MCP19215T-E/S8 adds essential communication and sensing capability for smart power systems; versus UCC28950PW, it trades raw analog timing precision for full firmware-defined control, protection, and diagnostics-making it optimal for adaptive, connected, and safety-critical designs.

FAQ
What is the maximum switching frequency supported by the MCP19215T-E/S8?
The MCP19215T-E/S8 supports a programmable switching frequency range from 31.25 kHz to 2.0 MHz. This range is set via firmware configuration of the internal oscillator and PWM timer registers. The upper limit ensures compatibility with high-frequency magnetics and low-profile inductors while maintaining stable peak-current-mode control across all operating conditions. The MCP19215T-E/S8 achieves consistent performance at 1.5 MHz in boost LED driver evaluations per Microchip AN2467.
Does the MCP19215T-E/S8 include an integrated microcontroller core?
Yes, the MCP19215T-E/S8 integrates a fully programmable 8-bit PIC microcontroller core with 8192 words of Flash program memory, 336 bytes of RAM, and a factory-calibrated 8 MHz internal oscillator accurate to ±1%. This core executes user firmware that configures PWM parameters, implements protection logic, processes ADC readings, and manages I²C/AUSART communication-making the MCP19215T-E/S8 a true system-on-chip for digital power applications.
How does the MCP19215T-E/S8 differ from the MCP19214T-E/S8?
The MCP19215T-E/S8 is the enhanced variant of the MCP19214T-E/S8, adding four key features: AUSART (TX/RX/CK/DT), two additional ADC channels (AN4, AN7), dual CCD modules (CCD1 on GPA6, CCD2 on GPB7), and two extra GPIOs (GPB1, GPB6). These additions enable full-duplex serial telemetry, expanded sensor monitoring, and hardware-accelerated timing capture-critical for automotive diagnostics and adaptive power control not possible with the MCP19214T-E/S8.
Is the MCP19215T-E/S8 qualified for automotive applications?
Yes, the MCP19215T-E/S8 is AEC-Q100 Grade 1 qualified (−40°C to +125°C) and PPAP-capable. It meets automotive reliability standards including HTOL, TC, ESD (HBM ≥2 kV), and electrical transients per ISO 7637-2. Its integrated LDO, thermal shutdown, and configurable UVLO/OVLO make it suitable for engine control units, body electronics, and ADAS power subsystems where robustness and traceability are mandatory.
What communication interfaces are available on the MCP19215T-E/S8?
The MCP19215T-E/S8 provides both I²C (SCL/SDA) and Addressable Universal Synchronous Asynchronous Receiver Transmitter (AUSART) interfaces. The AUSART supports asynchronous (TX/RX) and synchronous (CK/DT) modes, enabling firmware updates, real-time telemetry, and host-commanded reconfiguration. I²C allows PMBus-compatible power management communication, while AUSART permits custom protocols for diagnostics, calibration, or safety-critical status reporting in the MCP19215T-E/S8.
