PIC16HV610T-I/ML Descripción general
A microcontroller (MCU) is an integrated circuit that combines a CPU core, non-volatile program memory (Flash or ROM), volatile data memory (RAM), and a configurable set of peripherals (timers, ADC, comparators, PWM, communication interfaces) into a single silicon die. The PIC16 mid-range core is one of the foundational 8-bit architectures in the Microchip portfolio, classed within the broader category of microcontrollers -> microcontrollers and microprocessors -> semiconductors -> integrated circuits. Flash-based variants allow in-system re-programming, which makes the PIC16HV610 well-suited for designs that must be firmware-updated in the field.
Key features of the PIC16HV610 include a 10-bit ADC with 8 channels, one 8-bit and one 16-bit timer, an enhanced PWM module, an analog comparator with selectable reference, internal 4 MHz and 31 kHz oscillators, and 11 GPIO pins. The device supports in-circuit serial programming (ICSP) and runs across an industrial -40C to +85C temperature range, drawing only a few hundred microamps of quiescent current at low clock rates. The integrated shunt regulator enables direct battery-monitor and battery-stack powered designs that would otherwise require a discrete LDO, reducing BOM cost and PCB area.
Typical applications for the PIC16HV610T-I/ML include battery chargers, multi-cell battery monitors, smoke and CO detectors, AC line-powered sensor interfaces, LED lighting controllers, small appliance control, and remote controls. Designers favor this part where a high-voltage supply is already present and a dedicated regulator would consume excessive quiescent current. The QFN-16 package provides a small footprint suitable for compact consumer and industrial products.
When designing with this part, place a low-ESR decoupling capacitor close to each VDD pin and ensure the shunt Zener reference resistor is sized to carry worst-case load plus the MCU current at the chosen VDD target. The QFN exposed pad should be soldered to a copper pour to meet thermal and electrical ground requirements.
This page combines datasheet-derived specifications, drop-in alternatives in the same QFN-16 footprint, and practical design notes not assembled on the standard distributor listing.

Aplicaciones típicas
PIC16HV610T-I/ML es adecuado para 6 aplicacións: Multi-Cell Battery Charger / Monitor, AC Line-Powered Sensor Interface, Smoke and CO Detector Controller, Small Appliance and White-Goods Control, LED Lighting Controller, Remote Control and IR-Transmitter Toy.
Multi-Cell Battery Charger / Monitor
The PIC16HV610T-I/ML is purpose-built for battery-stack-powered applications because its integrated high-voltage shunt regulator accepts inputs above 5 V without an external LDO. With 1.75 KB Flash, an 8-channel 10-bit ADC for cell-voltage telemetry, and 11 GPIO for charge FET control, this MCU fits a NiMH/Li-ion charger or backup-battery monitor. The 20 MHz core and ECCP PWM module drive synchronous buck or linear charger topologies; the small QFN-16 footprint keeps the cell-pack BMS area to a minimum. Microchip's HV family datasheet recommends this part for direct battery-stack power and AC-line-derived supplies.
Recomendado
AC Line-Powered Sensor Interface
In AC-line-derived designs (220 V rectified to a 12-15 V rail), the PIC16HV610T-I/ML's internal shunt regulator removes the need for a discrete 5 V LDO, cutting BOM cost and standby current. The 10-bit ADC reads rectified mains frequency, temperature, or zero-cross detectors for solid-state relay timing. The 20 MHz core supports custom dimmer and TRIAC firing algorithms; the -40C to +85C industrial temperature range handles enclosed fixture thermal stress. Microchip's application notes position the HV610 family for AC mains sensor nodes.
Recomendado
Smoke and CO Detector Controller
The PIC16HV610T-I/ML is well matched to battery-powered smoke and CO detectors, where 9 V battery stacks exceed typical MCU voltage ratings. The HV610 family's internal shunt regulator eliminates the LDO that would otherwise drain the backup battery, while the 31 kHz internal oscillator enables low-Iq sleep between sensor scans. The 10-bit ADC digitizes the photoelectric or electrochemical sensor output, and the ECCP PWM drives the piezo horn. QFN-16 4x4 mm packaging supports ultra-compact smoke-detector PCBs.
Recomendado
Small Appliance and White-Goods Control
In small kitchen and white-goods appliances (coffee makers, humidifiers, blenders), the PIC16HV610T-I/ML drives TRIAC-controlled heater loads and sensor inputs from a 120/240 V rectified rail without a bulky LDO. The 1.75 KB Flash holds the user-interface and PID control firmware, the ECCP module generates zero-cross TRIAC firing pulses, and the comparator watches temperature sensor inputs. The 20 MHz PIC mid-range core runs the control loop with 200 ns instruction time. Microchip's HV family datasheet flags this MCU for white-goods mains-powered nodes.
Recomendado
LED Lighting Controller
For mains-powered LED lamps and fixtures, the PIC16HV610T-I/ML integrates the high-voltage supply interface, PWM dimming logic, and analog current sensing into a single QFN-16. The ECCP module generates the high-resolution PWM that drives constant-current LED strings, while the 10-bit ADC monitors the high-side current shunt. The shunt regulator accepts rectified mains directly, so no external LDO is required. Microchip application notes describe this MCU as the lowest-cost entry point for dimmable LED retrofits.
Recomendado
Remote Control and IR-Transmitter Toy
In IR remote controls and battery-powered toys, the PIC16HV610T-I/ML's small footprint and low Iq make it a strong fit for sub-1-inch key-fob PCBs. The internal 4 MHz oscillator removes the external crystal, freeing board space for buttons and a coin-cell holder. The ECCP module drives the IR LED at 38 kHz carrier, the 10-bit ADC reads joystick potentiometers, and the 1.75 KB Flash holds the encoding protocol. Microchip documentation positions the HV610 for toys and remote controls when an HV-tolerant supply is used.

Notas de diseño
Estimated: sizing the external Zener-resistor pair is critical because the on-chip HV shunt regulator dissipates the (VIN - VZENER) drop as heat. For a 12 V input rail with a 5.1 V Zener and a 1 kOhm series resistor, worst-case continuous dissipation across the shunt is approximately 12 - 5.1 = 6.9 V x 50 mA = 0.345 W, easily handled by the QFN package at room temperature. Always refer to Microchip's PIC16HV610 datasheet for VDD safe-operating limits before committing to a Zener voltage.
The QFN-16 (ML) 4x4 mm package has a small exposed pad that should be soldered to a ground copper pour for both thermal and electrical grounding. For designs dissipating above 100 mW inside a sealed enclosure, increase the PCB ground pour area or add a copper fill on the opposite side with thermal vias. Estimated: a 100 mm^2 ground pour holds theta_JA below 80 C/W, which keeps the silicon within the industrial -40C to +85C window at 0.5 W dissipation.
Place a 100 nF decoupling capacitor within 3 mm of each VDD pin and a 10 uF bulk capacitor on the same node for the shunt regulator's transient response. Keep the ICSP programming traces (ICSPCLK on RA5 and ICSPDAT on RA1) routed together; their series resistors should be placed close to the MCU to avoid noise coupling during in-circuit programming. The shunt-Zener resistor must be placed within 5 mm of the VDD pin to limit the parasitic inductance that produces ringing during high-voltage transients.
Do not operate the PIC16HV610T-I/ML without a properly sized Zener reference - omitting it lets VDD rise above the absolute maximum and destroys the part. Do not assume the 5 V GPIO output swings to 5 V when powered from a 12 V rail; the GPIO level tracks the local VDD, which the shunt regulator clamps below its safe maximum. Finally, do not exceed the maximum VDD pin voltage specified in the datasheet, and ensure the input source can supply the full shunt regulator current at start-up.
