PIC16HV753-I/ML Overview
A microcontroller (MCU) is a single-chip computer containing a CPU core, program memory, data RAM, and on-chip peripherals such as timers, ADC, communication interfaces, and GPIO. The PIC16 mid-range core is one of Microchip's classic 8-bit architectures using a 14-bit instruction word optimized for deterministic interrupt response and low-power operation. The PIC16HV753 sits inside the broader hierarchy: 8-bit MCU -> microcontroller -> embedded IC -> semiconductor device, and is the PIC family member optimized for high-voltage direct-supply applications like LED lighting, battery chargers, and motor control where eliminating an external regulator saves cost and board area.
Key features include an 8-channel 10-bit ADC, a 9-bit DAC, two high-speed analog comparators (50 ns response), an op-amp module, one Capture/Compare/PWM (CCP) peripheral, and a 32 kHz-to-20 MHz internal oscillator with 8 MHz factory calibration. The device also provides enhanced PWM, multiple timers, a watchdog timer, an on-chip voltage reference, and in-circuit serial programming (ICSP) via two pins. High-voltage variants integrate a 15 V shunt regulator on the supply pin so the chip can be powered directly from 9 V or 12 V rails.
Architecturally, the PIC16HV753 uses a Harvard RISC core with separate program and data buses, allowing instruction fetch and operand access in a single cycle. The high-voltage analog front-end is decoupled from the digital core through an internal regulator that generates the 2.0-5.5 V supply used by the core logic, giving designers a single-chip solution for direct-supply, mixed-signal embedded control.
Typical applications include AC mains-powered LED lighting drivers, switch-mode power supply (SMPS) primary-side control, sealed lead-acid battery chargers, 12 V fan/motor controllers, and industrial sensor signal conditioning where the on-chip op-amp, comparators, and ADC provide a complete analog front-end without external analog ICs.
When designing with this device, ensure the high-voltage supply current does not exceed the shunt regulator's load capability (typically a few mA) and place a 0.1 uF + 10 uF decoupling network close to the VDD pin. For in-circuit programming, dedicate the ICSPCLK/ICSPDAT pins and protect them from contention with application circuitry.

Typical Applications
PIC16HV753-I/ML is suitable for 6 applications: AC Mains-Powered LED Lighting Driver, Switch-Mode Power Supply (SMPS) Primary-Side Control, Sealed Lead-Acid / Lithium Battery Charger, 12 V Brushless DC (BLDC) / Brushed Fan Motor Controller, Industrial Sensor Signal Conditioning, Appliance User Interface / White-Good Control Panel.
AC Mains-Powered LED Lighting Driver
The PIC16HV753-I/ML's 2.0-15 V on-chip shunt regulator makes it ideal for AC mains-powered LED lighting drivers that derive an unregulated 12 V or 9 V DC bus directly from the rectified mains without a separate LDO. The 9-bit DAC and one op-amp can be configured as a precision constant-current reference for LED string regulation, while the 10-bit ADC samples the feedback divider to maintain target lumen output across temperature. With 3.5 KB of flash and 128 B of RAM, the chip implements PWM dimming and soft-start routines in a single 16-pin QFN footprint, eliminating external regulators and reducing total BOM cost for low-cost bulb and downlight designs.
Recommended
Switch-Mode Power Supply (SMPS) Primary-Side Control
The PIC16HV753-I/ML serves as the primary-side controller in low-power AC/DC and DC/DC SMPS designs, where it samples the auxiliary winding voltage via its 10-bit ADC and regulates the isolated output through the enhanced CCP PWM module. The high-voltage shunt regulator allows direct operation from a 12 V auxiliary winding without external regulation, and the 50 ns analog comparators provide cycle-by-cycle current-limit protection at switching frequencies up to 20 MHz instruction rate. The 3.5 KB flash holds the digital compensator firmware while the on-chip op-amp buffers the current-sense signal, enabling a compact, single-chip isolated supply implementation.
Recommended
Sealed Lead-Acid / Lithium Battery Charger
Battery charger designs benefit from the PIC16HV753-I/ML's on-chip high-voltage supply, which can be powered directly from a 12 V or 15 V DC adapter while the op-amp and 10-bit ADC monitor charge current and battery voltage to implement CC/CV (constant-current/constant-voltage) charging profiles. The 9-bit DAC provides programmable charge-current setpoint, and the 128 B of RAM is sufficient to hold state-machine variables for multi-stage charging (bulk, absorption, float). The -40C to +85C industrial temperature grade covers garage, automotive, and outdoor cabinet charger applications.
Recommended
12 V Brushless DC (BLDC) / Brushed Fan Motor Controller
Small 12 V BLDC or brushed fan controllers can run directly from the motor supply rail using the PIC16HV753-I/ML's on-chip high-voltage shunt regulator, eliminating an external LDO and reducing the BOM in cost-sensitive consumer and industrial fans. The enhanced CCP module generates 20 kHz switching PWM for FET commutation, while the 50 ns analog comparators implement back-EMF zero-crossing detection (sensorless BLDC) or stall detection (brushed). The 3.5 KB flash is adequate for speed-control PI loops and ramp-up/ramp-down profiles, and the small 16-pin QFN 4x4 mm package fits within the tight geometry of inline fan housings.
Recommended
Industrial Sensor Signal Conditioning
The PIC16HV753-I/ML's integrated analog peripherals (1 op-amp, 2 comparators, 1 10-bit ADC, 1 9-bit DAC) provide a complete single-chip signal-conditioning front-end for 4-20 mA current-loop sensors, RTDs, thermocouples, and bridge-type pressure transducers. The on-chip op-amp buffers and gain-stages the sensor signal, the 10-bit ADC digitizes it for linearization and scaling, and the 9-bit DAC generates the excitation current or offset trim. Industrial-grade -40C to +85C operation and direct 12 V/15 V supply capability make it well-suited to factory-floor transmitter designs where the sensor lives on the same 24 V loop as the controller.
Recommended
Appliance User Interface / White-Good Control Panel
White-good appliances (washing machines, dishwashers, refrigerators, microwave ovens) often share a 12 V or 15 V internal rail with the PIC16HV753-I/ML directly, allowing the chip to drive LED indicators, read capacitive or resistive touch buttons via the ADC, and control relays or triacs through its enhanced CCP PWM. The 3.5 KB flash fits typical UI state machines, the 128 B RAM holds menu state, and the 16-pin QFN 4x4 mm package fits behind a control-panel overlay. The high-voltage supply capability simplifies interfacing with mains-derived 12 V rails without an extra regulator stage.

Design Notes
The PIC16HV753-I/ML's on-chip HV shunt regulator can dissipate up to several hundred milliwatts when the supply bus sits at 12 V or 15 V while the core draws only a few mA. Decouple VDD with a 0.1 uF ceramic placed within 5 mm of the pin plus a bulk 10 uF electrolytic or tantalum to absorb transient current. Do not power the chip from a high-current source directly; the shunt regulator is intended for low-current logic-supply duties, and the bulk of high-voltage power should still pass through an external regulator or be supplied to downstream actuators separately.
The 16-pin QFN (4x4 mm) /ML package requires a properly designed land pattern with the exposed thermal pad soldered to a PCB ground pour for both thermal dissipation and electrical reference. Use 0.1 uF + 10 uF decoupling on VDD/VSS, route ICSP lines (ICSPCLK on RA1, ICSPDAT on RA0) away from switching traces, and add 4 k7 pull-ups on SDA/SCL if I2C peripherals are connected. Avoid via-in-pad for the thermal pad unless the fab supports micro-via; otherwise use 4-6 thermal vias in a star pattern to the inner ground plane.
Do not exceed the absolute-maximum VDD rating of 15 V on the HV variant or 5.5 V on the F variant, and ensure the shunt regulator load current does not exceed the datasheet figure (typically 5-10 mA). Configuration bits must be set for the correct oscillator mode (HFINTOSC vs external crystal) and the watchdog timer disabled for the application if not required. The op-amp output drives a limited load; do not connect low-impedance loads (< 1 kohm) directly without buffering. The 9-bit DAC output requires the CVREF capacitor for stable reference voltage in some configurations.
When using the PIC16HV753-I/ML's 50 ns analog comparators for SMPS current-limit or zero-crossing detection, keep comparator input traces short (under 10 mm) and route them away from PWM output traces to avoid capacitive coupling. The op-amp module has limited GBW; use it for DC or low-frequency signal conditioning, not for fast pulse amplification. For applications sensitive to ADC accuracy, add an external 0.1 uF + 10 uF VREF bypass network and avoid switching digital outputs during ADC conversions (set the A/D No-Operation bits in the appropriate configuration register).
Compliance Information
RoHS compliant per Microchip product page. The -I/ML industrial temperature grade is not AEC-Q100 qualified; for automotive applications requiring AEC-Q100, consult Microchip directly. The /ML package is Pb-free (lead-free).
