Product details
Overview
CYPD3196-24LDXS from Cypress Semiconductor is a single-chip, AEC-Q100 qualified USB Type-C port controller with integrated Arm® Cortex®-M0 MCU (64 KB Flash, 8 KB SRAM), full USB PD 3.0 v1.1 support including Programmable Power Supply mode, dual-port capability (one Type-C + one Type-A), and automotive-grade VBUS regulation (3.0–24.5 V input, ±8-kV contact ESD). It targets rear-seat automotive chargers requiring robust fault protection, legacy charging detection (QC 4.0, Apple 2.4A, AFC, BC 1.2), and system-level thermal/power management.
For engineers reviewing the CYPD3196-24LDXS datasheet, CYPD3196-24LDXS pinout, CYPD3196-24LDXS application, or CYPD3196-24LDXS equivalent, key selection criteria include its integrated shunt-based VBUS regulation, dual 8-bit SAR ADCs for temperature/current monitoring, wettable-flank 24-pin QFN package for automotive reflow inspection, and native support for BMC-encoded PD communication over CC lines without external transceivers.
Technical Context
The device implements a dedicated USB-PD physical layer with BMC encoder/decoder, hardware collision avoidance, and configurable RP/RD termination for DFP role enforcement. Its high-voltage regulator supports constant-voltage and constant-current VBUS control via feedback pin (FB) and integrates low-side current sense amplifier (CSA) with 100 mA resolution across 5 mΩ shunt.
Two integrated PFET gate drivers (VBUS_P_CTRL with active pull-up; VBUS_C_CTRL requiring external pull-up) manage power path switching, while four VBUS-short-protected pins (CC1, CC2, P2.2, P2.3) withstand up to 22 VDC for 1000 hours-critical for automotive connector layout where CC pins neighbor VBUS.

Equivalent & Alternatives
The following parts are listed as comparable options for similar USB Type-C port controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STUSB4500QTR | Lacks integrated MCU, flash, and ADCs; relies on external host processor for PD policy engine and thermal management | Suitable for cost-sensitive non-automotive chargers where firmware customization is unnecessary | Select when BOM simplicity outweighs need for autonomous fault response or field-upgradable charging profiles |
| TPS65987DRLR | Higher integration includes integrated DC/DC converter; no native legacy charger detection blocks for QC/AFC/Apple | Better suited for laptop dock applications requiring 100 W PD delivery but no proprietary charging support | Choose only if system already implements separate legacy charging IC and requires higher PD power delivery than CYPD3196's 60 W limit |
Compared with STUSB4500QTR and TPS65987DRLR, CYPD3196-24LDXS uniquely combines automotive-grade robustness, on-chip firmware programmability, and native multi-protocol legacy charging-making it the only option for AEC-Q100-compliant single-chip automotive chargers needing QC 4.0 + PD 3.0 coexistence.

FAQ
What is the maximum USB PD power delivery capability supported by CYPD3196-24LDXS?
CYPD3196-24LDXS supports USB PD 3.0 v1.1 up to 60 W (20 V @ 3 A) with Programmable Power Supply mode. Its integrated VBUS regulation loop and current sense amplifier enable precise constant-current control during PPS negotiation, but hardware current limits and thermal design constrain sustained output to 60 W in automotive ambient conditions.
Does CYPD3196-24LDXS require an external crystal or oscillator?
No external crystal or oscillator is required. The device includes a factory-trimmed internal oscillator that meets USB PD timing accuracy requirements for BMC encoding/decoding. This eliminates BOM cost and board space associated with external timing components while maintaining ±1.5% frequency stability across –40 °C to +105 °C.
How does the VBUS short protection work on CC1 and CC2 pins?
CC1 and CC2 pins feature dedicated high-voltage protection circuitry that clamps transient voltages up to 22 VDC for 1000 hours. During accidental shorts to VBUS, internal diodes divert current away from sensitive PHY circuitry, and the device maintains functionality without latch-up-verified per AEC-Q100 stress testing protocols.
Can CYPD3196-24LDXS operate without firmware programming?
No. The device ships with blank flash and requires firmware configuration via SWD interface to define PD contracts, charger detection profiles, fault response behavior, and GPIO mappings. Cypress provides EZ-PD Configuration Utility and SDK examples, but functional operation is impossible without customer-specific firmware loading.
